Abstract

AbstractA general covariant scheme is proposed for the kinematical analysis of arbitrary reactions. By this scheme the problem of finding invariant amplitudes and corresponding kinematical covariants can be solved systematically. The amplitudes are labelled by two invariant indices for each particle related to spin and parity. The method provides a tool for exploiting the symmetries of the M‐function, including crossing symmetry and the Pauli principle. Amplitudes free from kinematical singularities can easily be constructed.
