Pion Fusion in Peripheral Collisions
arXiv:hep-ph/9410402 · doi:10.1103/PhysRevD.52.6616
Abstract
We estimate the cross section for quasi-elastic double pion exchange in high energy proton-proton collisions. Total and elastic cross sections are calculated in an equivalent pion approximation, with pion-baryon vertices taken from chiral perturbation theory.
