2. Particle Decays: Relativistic. 5+10 minutes. 20 points. CA) junt aorwe a) An elementary particle physicist wants to know if she should set up an experiment to make the measurement of a single photon resulting from an unstable particle of mass M. Consider such a decay and give her the best advice you can. (b) Consider whether it is kinematically possible for a zero mass particle (like a photon, except it is unstable) to decay into two zero mass particles. Consider the most general setup, and provide all information that you can
