![**Problem 3.15**
A pion traveling at speed \( v \) decays into a muon and a neutrino, \( \pi^- \rightarrow \mu^- + \overline{\nu}_\mu \). If the neutrino emerges at 90° to the original pion direction, at what angle does the muon come off?
**Answer:**
\[
\tan \theta = \frac{(1 - m_\mu^2 / m_\pi^2)}{(2 \beta \gamma^2)}
