Effect of the Coulomb interaction in A(d,p) fragmentation

Abstract

In the framework of Glauber-Sitenko model we calculate contribution of Coulomb interaction in cross-section of A(d,p) reaction at high energy and zero angle. It is demonstrated that such effect significantly increases the differential cross section only at peak, where the proton momentum $p$ is near half of the deuteron momentum $p_d$ in lab. frame, $p \sim \frac12 p_d$. The Coulomb interaction do not change the results in the high momentum region, where quark effects should be taken into account.
