Problem

Use the result of Problem 3.14 to find the threshold energies for the following reactions, assuming the target proton is stationary: (a)

p + p \to p + p + \pi^0

(b)

p + p \to p + p + \pi^+ + \pi^-

(c)

\pi^- + p \to p + \bar{p} + n

(d)

\pi^- + p \to K^0 + \Sigma^0

(e)

p + p \to p + \Sigma^+ + K^0
