Abstract:

The helicity formalisim is developed in detail and used to obtain final state angular distributions in relativistic scattering and decay processes. The topics covered include properties of rotation operators, construction of helicity states, scattering and decay amplitudes, the parity of helicity states, and the treatment of identical particles.
