WebTau decay rate as a function of the final muon energy E µ and direction (inset) for tau with energy E τ = 10 GeV. Here θ µτ is the opening angle between the muon and its parent tau. Web2 Muon Decay Lifetime Calculation The decay process is !e+ e+ . We’ll do our labeling with subscripts. We’ll de ne the muon as particle 1, the muon neutrino as particle 2, the elec-tron neutrino as particle 3, and the electron as particle 4. Let’s construct M using the Feynman Rules. 1. i, since the presented Feynman rules are for iM. 2.

The lifetime of an individual particle cannot be predicted, but a statistical distribution can be specified for a large sample. Equivalently, one can express it in terms of the decay rate, Γ, which is the probability per unit time that a given particle will decay.
WebK is the rate constant, expressed in reciprocal of the X axis time units. If X is in minutes, then K is expressed in inverse minutes. Tau is the time constant, expressed in the same … WebThe total decay rate can be determined form the condcutivity decay rate and the radiative decay rate can be determined from the total photoluminescence decay rate.
