Particles and fields: theoretical physics

4) Relativistic Mechanics: it\" Decay The decay of a n'J-meson with rest mass m0 and momentum p = (0, 0, 3/4 mo) into two photons results in one photon being emitted in the same direction as the original pion and the other photon being emitted in the opposite direction. Determine the energy and momentum of the photons, as well as the four-momentum of all particles
