Study Notes
Particle Physics
- Pair annihilation occurs when a particle and its antiparticle collide, converting their mass into energy and producing two gamma rays.
- Leptons are indivisible point objects that do not experience the strong nuclear force, examples include electrons, positrons, and neutrinos.
Hadrons
- Hadrons are subatomic particles that experience all fundamental forces, including the strong nuclear force.
- Hadrons are composed of quarks, which are fundamental building blocks.
- Baryons are hadrons composed of three quarks or three antiquarks.
- Mesons are hadrons composed of a quark-antiquark pair.
Quarks
- Quarks come in six flavors: up (u), down (d), strange (s), charmed (c), top (t), and bottom (b).
- Each quark has a corresponding anti-quark with opposite charge and same mass.
Neutrinos
- Neutrinos are subatomic particles produced in beta decay with very little mass and no electric charge.
- Neutrinos are emitted during beta radiation along with an electron (beta particle).
- Neutrinos carry momentum and energy, conserving both quantities.
Antimatter
- Antimatter is composed of antiparticles, which are identical to particles in mass but opposite in electric charge.
- Each particle has its own antiparticle, such as the positron (antiparticle of the electron).
Particle Interactions
- When protons collide, the kinetic energy is converted into new particles, conserving electric charge, mass-energy, and momentum.
- Pair production occurs when a gamma photon creates a subatomic particle and its antiparticle, following the laws of conservation.

Description
Learn about neutrinos, subatomic particles with little mass and no charge, produced during beta decay. Understand how neutrinos are emitted alongside electrons in beta radiation, conserving momentum and energy. Explore the equation for this process: 0n 1 → 1p 1 + −1e 0 + 0 0
