Question

Muons are produced through the annihilation of particle a and its antiparticle, namely the process, a+a¯μ++μ A muon has a rest mass of 105MeVc2 and its proper life time is 2μs . If the center of mass energy of the collision is 2.1GeV in the laboratory frame that coincides with the center – of – mass frame, then the fraction of muons that will decay before they reach a detector placed 6 km away from the interaction point is – (June)
