Comparison of theoretical and experimental nonleptonic hyperon decay amplitudes
Description
It is shown that fitting Pauli amplitudes instead of Dirac amplitudes reduces substantially the mismatch in fits to experiment of theoretical parity-violating and parity-conserving nonleptonic hyperon decay amplitudes for massless pions obtained from current algebra and PCAC, effective chiral lagrangians, or lowest order chiral perturbation theory.
