Fermions TU Dresden Particles of the Standard Model Sophie Koßagk

Quarks fractional electric charge Colour charge Colour confinement Baryons (three quarks) and Mesons (two quarks) have an integer electric charge and they are colour neutral TU Dresden Particles of the Standard Model Sophie Koßagk Fig.: [5] Fig. : [6]

Leptons do not carry colour charge Are not influence by strong force Electron, muon, tau are single negative charged Neutrinos has no charge TU Dresden Particles of the Standard Model Sophie Koßagk
