Coherent state formulation of pion radiation from nucleon-antinucleon annihilation
Physical Review C1994Vol. 50(2), pp. 640–651
Abstract
We assume that nucleon-antinucleon annihilation is a fast process leading to a classical coherent pion pulse. We develop the quantum description of such pion waves based on the method of coherent states. We study the consequences of such a description for averages of charge types and moments of distributions of pion momenta with isospin and four-momentum conservation taken into account. We briefly discuss the applicability of our method to annihilation at rest, where we find agreement with experiment, and suggest other avenues for its use.
