Question:
The probability for an individual particle to have not yet decayed after a time t since its creation is given by prob(t) = e-t/τ, where t is the mean lifetime of the particle.
(a) What is the probability that a π+ at rest will still exist after 0.10 ms?
(b) What is the probability that a π+ of momentum 500 MeV/c can travel a distance of 20 m before decaying? Consider time dilation.
(c) What is the probability that a φ particle with the same momentum could travel the same distance?
