= Introduction =

Particle physics asks a simple-sounding question with a deep answer: '''What is matter made of, and how do its smallest known building blocks interact?''' The [[English:Standard Model|Standard Model]] is the best-tested framework we currently have for answering most of that question. It describes elementary matter particles, three fundamental interactions, and the [[English:Higgs boson|Higgs boson]]. It does not include a quantum theory of gravity, and it does not explain several major observations such as dark matter.

This aiMOOC is designed for '''Grades 11–13'''. You will connect ideas from [[English:Quantum physics|quantum physics]], [[English:Electric charge|electric charge]], [[English:Radioactivity|radioactivity]], [[English:Special relativity|special relativity]], and experimental science. You do not need university-level quantum field theory, but you should be comfortable with scientific notation, conservation laws, energy, momentum, and basic algebra.

By the end of the course, you should be able to classify Standard Model particles, explain the roles of quarks, leptons, and bosons, interpret simple interaction diagrams, describe how collider experiments test theoretical predictions, and evaluate why physicists continue to search for physics beyond the Standard Model.

The diagram above organizes the known elementary particles of the Standard Model. Use it as a reference, but remember that a table of particles is only the beginning: the model also specifies the rules governing their interactions.

= From Atoms to Elementary Particles =

For much of the history of science, atoms were treated as the smallest pieces of matter. Experiments later showed that atoms contain electrons surrounding nuclei, and that nuclei contain protons and neutrons. Protons and neutrons are not elementary: they are built from quarks. Electrons, by contrast, are elementary as far as current experiments can determine.

In particle physics, an '''elementary particle''' is one that has no experimentally resolved internal structure. This definition is empirical: if future experiments reveal substructure inside a particle now considered elementary, our classification would have to change.

The Standard Model separates elementary particles into two broad groups. '''Fermions''' are the matter particles. '''Bosons''' include the particles associated with interactions and the Higgs boson. All Standard Model fermions have spin one-half. The photon, gluons, and W and Z bosons have spin one, while the Higgs boson has spin zero.

{{BR}}
== The Three Generations of Matter ==

The twelve fundamental matter particles are six quarks and six leptons. They occur in three generations. The first generation contains the lightest stable matter particles, while particles in the second and third generations are heavier and normally decay into lighter particles.

{| class="wikitable"

|-
| Leptons
| electron and electron neutrino
| muon and muon neutrino
| tau and tau neutrino
| Charged leptons have charge -1 e; neutrinos are electrically neutral
|}

Each matter particle also has an [[English:Antiparticle|antiparticle]] with the same mass and opposite values for additive quantum numbers such as electric charge. An electron's antiparticle is the positron. A quark's antiparticle is an antiquark.

{{#ev:youtube|https://www.youtube.com/watch?v=cobkYfK9zyg|500|center}}

{{BR}}
= Quarks, Hadrons, Protons, and Neutrons =

Quarks carry fractional electric charge and a type of strong-interaction charge called '''colour charge'''. The words red, green, and blue are labels for the three colour states; they do not describe visible colours.

Quarks are not observed as isolated particles in ordinary conditions. The strong interaction confines them into composite particles called [[English:Hadron|hadrons]]. In the simplest classification, '''baryons''' contain three valence quarks and '''mesons''' contain a quark and an antiquark. More complicated hadrons such as tetraquark and pentaquark states also exist.

A proton has the valence-quark composition '''uud'''. Its charge is therefore +2/3 + 2/3 - 1/3 = +1 in units of the elementary charge. A neutron has the valence-quark composition '''udd''', giving total charge 0. This arithmetic is a useful first model, but most of a proton's mass does not come from simply adding the small masses of its quarks. Much of the proton's mass-energy arises from the dynamics of quarks and gluons in quantum chromodynamics.

{{BR}}
== The Strong Interaction and Quantum Chromodynamics ==

The theory of the strong interaction is [[English:Quantum chromodynamics|quantum chromodynamics]], usually abbreviated QCD. Its force carriers are eight types of [[English:Gluon|gluons]]. Gluons themselves carry colour charge, so they can interact with one another. This makes QCD very different from ordinary electromagnetism, where photons do not carry electric charge.

At very short distances and high energies, quarks interact more weakly, a property called '''asymptotic freedom'''. At larger distances relevant to hadrons, the interaction becomes strong and leads to confinement. When energetic quarks are produced in a collider, they do not appear as free quarks; instead they produce sprays of hadrons called '''jets'''.

{{BR}}
= Leptons and Neutrinos =

The six leptons are the electron, muon, tau, and their three corresponding neutrinos. The electron, muon, and tau have electric charge -1. Neutrinos have no electric charge and interact through the weak interaction; this makes them difficult to detect.

Neutrinos can change flavour as they travel, a phenomenon called [[English:Neutrino oscillation|neutrino oscillation]]. Oscillations require differences between neutrino masses, showing that neutrinos have nonzero masses. The simplest original form of the Standard Model treated neutrinos as massless, so neutrino mass is an important clue that the minimal model must be extended.

Muons and taus resemble heavier versions of the electron in their electric and weak interactions, but they are unstable. The muon is long-lived by particle-physics standards and is common in cosmic-ray showers at Earth's surface.

{{BR}}
= Fundamental Interactions and Carrier Bosons =

Physicists describe four fundamental interactions in nature: electromagnetic, strong, weak, and gravitational. The Standard Model contains the first three. Gravity is described extremely well on large scales by general relativity, but a complete quantum description of gravity is not part of the Standard Model.

{| class="wikitable"

|}

A force-carrier picture is useful, but quantum field theory goes deeper: particles are excitations of underlying fields, and interactions are calculated from the couplings among those fields.

{{BR}}
== Electromagnetism ==

In quantum electrodynamics, or QED, the photon is the quantum of the electromagnetic field. The photon is electrically neutral and massless. Because the photon is massless, electromagnetic effects can act over very long distances, although opposite charges can screen one another in matter.

A photon's energy is related to its frequency by <math>E = hf</math>, where <math>h</math> is Planck's constant. This is one bridge between particle language and wave language: the same electromagnetic field can be described in terms of waves or photons.

{{BR}}
== The Weak Interaction ==

The weak interaction is carried by the charged W+ and W- bosons and the neutral Z boson. These carriers are very massive compared with the photon, which helps explain why the weak interaction has an extremely short effective range.

The weak interaction can change quark flavour. In beta-minus decay, for example, a down quark changes into an up quark while emitting a W- boson. The W- then produces an electron and an electron antineutrino. At the nucleon level, this changes a neutron into a proton.

[[File:Beta decay artistic.svg|500px|frameless|center]]

The diagram is a compact representation of the beta-minus process. It should not be interpreted as a literal photograph of particles travelling along fixed paths.

{{#ev:youtube|https://www.youtube.com/watch?v=yOiABZM7wTU|500|center}}

{{BR}}
= Feynman Diagrams: A Language for Interactions =

[[English:Feynman diagram|Feynman diagrams]] are graphical tools used to organize calculations in quantum field theory. External lines represent incoming or outgoing particles, internal lines represent propagators, and vertices represent allowed interactions. A diagram helps you track charge, particle type, and possible interaction routes.

A common misunderstanding is that a Feynman diagram is a tiny movie showing exactly what happened. It is not. In quantum field theory, measurable probabilities come from probability amplitudes, and several allowed diagrams can contribute to the same observed process. The diagrams are terms in a mathematical calculation.

When you inspect a simple diagram, ask three questions: Which particles enter and leave? Which conservation laws apply? Which Standard Model interaction permits each vertex?

{{#ev:youtube|https://www.youtube.com/watch?v=hk1cOffTgdk|500|center}}

{{BR}}
= Electroweak Unification and the Higgs Field =

At everyday energies, electromagnetism and the weak interaction look very different. In the Standard Model they are two aspects of a single '''electroweak''' theory. The unification is based on a gauge symmetry that is hidden at low energies by the Brout-Englert-Higgs mechanism.

The [[English:Higgs field|Higgs field]] has a nonzero value throughout empty space. Elementary particles that couple to this field can acquire mass. The W and Z bosons become massive, while the photon remains massless. Fermion masses arise through their couplings to the Higgs field as well.

This statement needs an important qualification. The Higgs mechanism explains the masses of elementary Standard Model particles, but it does not mean that all the mass of ordinary matter comes directly from the Higgs field. Most of the mass of protons and neutrons comes from QCD energy associated with confined quarks and gluons.

The [[English:Higgs boson|Higgs boson]] is a quantum excitation of the Higgs field. ATLAS and CMS announced the discovery of a new boson consistent with the predicted Higgs particle in 2012. Its measured properties have continued to agree closely with Standard Model expectations.

[[File:Candidate Higgs Events in ATLAS and CMS.png|500px|frameless|center]]

[[File:3D view of an event recorded with the CMS detector in 2012 at a proton-proton centre of mass energy of 8 TeV.png|500px|frameless|center]]

The CMS event display above shows a proton-proton collision with features expected from a Higgs boson decaying to two photons, although individual candidate events can also arise from background processes. Particle discoveries therefore rely on statistical patterns across many events, not on a single striking picture.

{{#ev:youtube|https://www.youtube.com/watch?v=QG8g5JW64BA|500|center}}

{{BR}}
= The Standard Model as a Gauge Theory =

For learners ready for a more advanced view, the Standard Model is a relativistic quantum field theory based on the gauge symmetry

<math>SU(3)_C \times SU(2)_L \times U(1)_Y.</math>

The '''SU(3)''' part describes the colour symmetry of QCD. The '''SU(2) × U(1)''' part describes the electroweak interaction before symmetry breaking. The Higgs field changes the low-energy form of the electroweak symmetry so that the photon remains massless while the W and Z bosons become massive.

The mathematical structure determines which particles can interact, which quantities are conserved, and how strongly different processes occur. Coupling constants and particle masses are measured experimentally and inserted as parameters of the theory. The Standard Model then makes quantitative predictions that can be tested.

Quark flavours can mix through the CKM matrix, so weak interactions can transform one quark flavour into another. Neutrino flavours also mix, described by a different matrix. These mixing phenomena are central to modern precision tests of particle physics.

{{BR}}
= Antimatter, Symmetry, and Conservation Laws =

For every elementary matter particle, the Standard Model includes an antiparticle. When a particle and its antiparticle meet, they can annihilate into other particles if all relevant conservation laws are satisfied. The reverse process is also possible: sufficient energy can produce a particle-antiparticle pair.

The relation <math>E = mc^2</math> explains why energy in a collision can become rest mass and why mass can be released as energy. However, energy alone does not determine which final state is possible. Electric charge, momentum, angular momentum, colour, and other quantum numbers constrain particle reactions.

[[English:CP violation|CP violation]] is a subtle asymmetry between matter and antimatter that occurs in weak interactions. The Standard Model contains CP violation, but the amount known in the quark sector is not enough by itself to explain why the observable universe contains so much more matter than antimatter. This is one reason physicists look for additional sources of asymmetry.

{{BR}}
= How Particle Physicists Test the Model =

Particle physics combines theory with extremely precise experiments. Accelerators use electric fields to increase the energy of charged particles and magnets to steer and focus beams. When beams collide, some of their kinetic energy can be converted into new particles, provided conservation laws allow the process.

[[File:Large Hadron Collider at CERN map.svg|500px|frameless|center]]

The Large Hadron Collider, or LHC, is a circular accelerator at CERN near Geneva. Its large experiments include ATLAS and CMS, which are general-purpose detectors designed to reconstruct many kinds of collision products.

[[File:CERN LHC ATLAS Detector.jpg|500px|frameless|center]]

A collider detector is built in layers. Tracking detectors measure the paths of charged particles in magnetic fields. Calorimeters measure energy deposited by electromagnetic or strongly interacting particles. Muon systems identify penetrating muons. Neutrinos usually leave the detector without direct interaction, so their presence is inferred from missing momentum and energy in the plane transverse to the beams.

[[File:Event display of a 4-muon candidate in the ATLAS detector.png|500px|frameless|center]]

The four-muon ATLAS event shown above has a reconstructed four-lepton mass near 125 GeV. Event displays help scientists inspect complex collisions, but conclusions come from calibrated data, uncertainty estimates, background models, and statistical analysis across large samples.

{{#ev:youtube|https://www.youtube.com/watch?v=UDoIzvKumGI|500|center}}

{{BR}}
== From Tracks to Evidence ==

A new particle is rarely seen directly. Most unstable particles decay too quickly to cross a detector. Instead, physicists infer them from the energies, momenta, charges, and identities of longer-lived decay products.

One powerful idea is '''invariant mass'''. If several measured particles came from one parent particle, their combined energy and momentum can be used to reconstruct the parent's mass. A concentration of events around the same reconstructed mass can signal a resonance. Researchers compare the observed distribution with predicted backgrounds and quantify the probability that an apparent excess could arise from statistical fluctuations.

Systematic uncertainties are equally important. Detector calibration, theoretical modelling, particle-identification efficiency, luminosity measurements, and background estimates can all affect a result. Good experimental physics therefore combines statistics, engineering, computing, and careful reasoning.

{{BR}}
= Successes and Limits of the Standard Model =

The Standard Model has survived a huge range of experimental tests. It correctly predicted particles such as the W and Z bosons before they were directly observed, provides highly accurate descriptions of electromagnetic and weak processes, explains the strong interaction through QCD, and includes the Higgs mechanism confirmed by the discovery of the Higgs boson.

Yet the Standard Model is not a complete theory of nature. Important open questions include the following.

{| class="wikitable"
! Open question
! Why it matters
|-
| Quantum gravity
| Gravity is not included in the Standard Model, and a consistent quantum theory of gravity remains an open goal.
|-
| Dark matter
| Astronomical observations require additional gravitating matter, but no confirmed Standard Model particle has the needed properties to explain all dark matter.
|-
| Neutrino masses
| Neutrino oscillations show that neutrinos have mass, requiring an extension of the minimal Standard Model description.
|-
| Matter-antimatter asymmetry
| Known Standard Model CP violation is not enough to account for the observed cosmic dominance of matter.
|-
| Parameter values and generations
| The model contains measured masses, mixing angles, and couplings but does not explain why they have their particular values or why there are three generations.
|}

A good scientific theory does not need to answer every question to be valuable. The Standard Model is powerful precisely because it makes specific, testable predictions. Its unexplained features guide the design of new experiments and theories.
