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

Difference between Pions and Kaons

Kaons are strange with the exeption of π ⁰
