A pi–meson (mass = 139.6 MeV/c2) decays into a mu–meson (mass = 105.7 MeV/c2) and a neutrino (mass = 0). Calculate the kinetic energies of the mu–meson and the neutrino in in the rest frame of the pi–meson
I have uploaded answer of total 4 pages in which the 2 pages have pre information and the answer starts frim page 3.
Kinetic energy of mu meson is written in positive because energy can't be described in negative and kinetic energy of neutino is equal to E(neutrino).
