Physics 5110 Homework 3 (due Feb 3) January 26, 2010 1. The π + meson has a mean lifetime (at rest) of 2 . 6 × 10 - 8 s. Its prin- cipal decay modes are μ + ν μ and e + ν e with branching fractions of ap- proximately 0.99988 and 0.00012, respectively. Determine the partial transition rates. 2. Williams, problem 2.8. 3.
