Hadron-nucleus scattering in the local reggeon model with pomeron loops for realistic nuclei

TL;DR

This paper investigates hadron-nucleus scattering using the local reggeon model, revealing that within the nucleus, the supercritical pomeron becomes subcritical, enabling perturbative analysis and causing oscillations in the cross-sections.

Contribution

It demonstrates the transformation of the supercritical pomeron into a subcritical one inside the nucleus, allowing perturbative treatment and analyzing pomeron loop effects.

Findings

Supercritical pomeron becomes subcritical inside the nucleus.

Pomeron intercept becomes complex, leading to oscillations.

Perturbative treatment of loops is feasible in this regime.

Abstract

Contribution of simplest loops for hadron-nucleus scattering cross-sections is studied in the Local Reggeon Field Theory with a supercritical pomeron. It is shown that inside the nucleus the supercritical pomeron transforms into a subcritical one, so that perturbative treatment becomes possible. The pomeron intercept becomes complex, which leads to oscillations in the cross-sections.
