The mass of a tau particle is 1777MeV/c2. The mass of the muon is 106MeV/c2. A tau decays and generates a muon with opposite momentum with one neutrino and the other neutrino carries zero momentum. If the tau was stationary in your frame, compute the distance the muon has travelled (lifetime 106sec)?

Answer rating: 100% (QA)

To calculate the distance travelled by the muon we need to use the concept of relativistic decay The ... View the full answer
