[QUOTE="vela, post: 4503741, member: 221963"] A few suggestions: [LIST=1] [*]Avoid using ##\gamma## and any velocities. It just makes the algebra more painful. Work only with energy, momentum, and mass instead. For example, the kinetic energy is given ##E-mc^2##. [*]Use the relationship ##(mc^2)^2 = E^2 - (pc)^2##. [/LIST] Your equation for conservation of energy is incorrect. Kinetic energy obviously is not conserved. Initially there is no kinetic energy because the pion is at rest whereas the muon and neutrino do have kinetic energy. It's total energy E that's conserved. [/QUOTE]
