Problem

Particle

A

decays into three or more particles:

A \longrightarrow B + C + D + \cdots

(a) Find the maximum and minimum energies that particle

B

can have in terms of the rest masses of the other particles in the problem. (b) For the decay

D^0 \longrightarrow K^- + \pi^- + e^+ + \nu_e

, find the maximum and minimum energies the

e^+

can have.
