Lepton Definition
Fundemental particles that only interact with the weak force
Lepton Examples
Electron, Muon, Tau, Neutrino, + respective neutrinos and anti-particles
Hadron Defentition
A particle that is not fundemental and interacts with both the strong and weak force
Baryon Defention
A particle made up of 3 quarks/antiquarks that can decay into a proton
Baryon Examples
Proton, Neutron, + respective antiparticles
Meson Defentition
A particle that is made of a quark and antiquark pair
Meson Examples
Pions, Kaons + respective antiparticles
