Selection Rules for NN¯ Annihilation
Abstract
Selection rules governing the annihilation of a nucleon-antinucleon pair into pions, photons, and heavy mesons are derived from the conservation of angular momentum, parity, charge parity, and isotopic spin. Special attention is given to the probability of annihilation purely into neutral pions.
