S-wave $\pi^0$ production In pp Collision In A Covariant OBE Model

Nuclear Theory 2016-09-08 v1

Abstract

The total cross section for the pp to pp π0\pi^0 reaction at energies close to threshold is calculated in a covariant one-boson-exchange model. The amplitudes for the elementary BN to Nπ0\pi^0 processes are taken to be the sum of s, u and t pole terms. The main contributions to the primary productionamplitude is due to a sigma meson exchange. Both the scale and energy dependence of the cross section are perfectly reproduced.
