A neutral pion, π0, moving at 0.999c relative to the lab frame decays into two massless particles. One particle moves in the same direction as the pion did while the other moves in the opposite direction. The pion has a mass of 135 GeV/c2. What are the energy and momentum of the massless particles as measured in the lab frame? As measured in the pion’s rest frame?
