2. Consider the decay of a parent particle M to two identical particles: M > can. Hint: for the twobody decay, work in the rest frame of the parent particle and consider conservation of energy and momentum. (a) What is the largest mass particle a. may have in this decay? Express your answer in terms of the parent particle mass, M. (b) For the specic decay of the neutral pion, 71'\" > 77, what is the energy of the daughter photons? (mfg = 135 MeV/c2 and m7 = 0) (c) For the specic decay of the neutral K 0 > wear\
