1 Phys 571 , Fall 2010 Assignment #3 Due: 9/22/2010 1. π0-meson moving with velocity v decays into two photons ( massless quanta of EM ﬁeld). In the proper frame of π0 distribution of photons is spherically symmetric. Find the distribution of photons in the laboratory frame. 2. Express energy of π0 meson from the previous problem via the ratio f of the number of photons radiated into the forward hemisphere to the number of photons radiated into the backward one. 3. A particle of mass m and momentum p decays into two particles. Given the momentum
