SUMMARY
The maximum scattering angle for the collision process \(\nu_\mu e \rightarrow \nu_\mu e\) is determined to be \(\sqrt{\frac{2 m_e}{E_e}}\), where the electron is stationary in the lab frame and the energy after the collision is significantly greater than the electron mass (\(E >> m_e\)). This result is notable as it remains independent of the neutrino's energy, which is counterintuitive since one might expect the neutrino's energy to influence the scattering angle. The discussion emphasizes that a higher neutrino energy results in a smaller deflection angle for the neutrino at a given energy transfer.
