Nuclear & Particle Physics
MeV (Mega-electronvolts)
The net amount of energy released or absorbed during a nuclear reaction or radioactive decay process.
Q = (m_reactants - m_products) c²
Quantum Chromodynamics (QCD)
Nuclear & Particle Physics
Non-Abelian Gauge Theory
The relativistic quantum field theory describing the strong nuclear interaction between color-charged quarks and gluons.
L_QCD = q̄ (i γ^μ D_μ - m) q - ¼ G^a_μν G^a,μν
Quark Flavor
Nuclear & Particle Physics
Quantum Numbers (S, C, B, T)
The quantum property that distinguishes the six fundamental types of quarks in the Standard Model.
6 Flavors: u, d, c, s, t, b
Quarks
Nuclear & Particle Physics
Fractional Elementary Charge e
Fundamental spin-1/2 elementary particles that experience all four fundamental interactions and combine via the strong force to form hadrons.
q = +⅔ e (u, c, t), q = -⅓ e (d, s, b)
