Unformatted text preview: Yes L µ Muon Lepton Number Yes L τ Tau Lepton Number Yes L Overall Lepton Number L = L e +L µ +L τ Yes Not all particles carry every label. The particles are only labeled by the quantum numbers that are conserved for that particle. • Particles with integral spin J (J = 0, 1, 2, …) are called bosons . • Particles with half-integral spin J (J = ½, 3/2, …) are called fermions . • Particles with spin-parity J P = + are refered to a scalars , -are pseudo-scalars , 1-are vectors , 1 + are pseudo-vectors , 2 + are tensors , etc. • Hadrons are labeled by I G J PC ....
