In particle physics, particle decay is the spontaneous process of one unstable subatomic particle transforming into multiple other particles. The particles created in this process (the final state) must each be less massive than the original, although the total invariant mass of the system must be conserved. A particle is … Ver mais Particle decay is a Poisson process, and hence the probability that a particle survives for time t before decaying is given by an exponential distribution whose time constant depends on the particle's velocity: Ver mais This section uses natural units, where $${\displaystyle c=\hbar =1.\,}$$ The mass of an unstable particle is formally a complex number, with the real part being its mass … Ver mais • J.

WebTo illustrate the lepton number conservation law, consider the following known two-step decay process: π + → μ + + ν μ μ + → e + + ν e + ν — μ. In the first decay, all of the lepton numbers for π + are 0. For the products of this decay, L μ = −1 for μ + and L μ = 1 for ν μ. Therefore, muon-lepton number is conserved.
