Muon and Tau Lepton Decays



In this chapter we study the τ ± (tau lepton) and μ ± (muon) decays governed by weak interactions only. Since the leptonic numbers are assumed to be strictly conserved in the standard model, the electromagnetic decay modes τ ±μ ±(e±)+γ and μ ± → e±+ γ cannot occur. See Problem 12.1, however.
