Triple-pomeron amplitude in the effective action approach

TL;DR

This paper calculates the imaginary part of the triple pomeron amplitude using the effective action approach, revealing a simple dependence on longitudinal momentum transfer, and applies this to high-mass diffraction and double scattering cross-sections.

Contribution

It introduces a novel calculation of the triple pomeron amplitude's imaginary part within the effective action framework, highlighting a simple $1/| ext{e}|$ dependence.

Findings

Dependence on longitudinal momentum transfer separates as $1/|\text{e}|$

Results applied to high-mass diffraction on hadrons

Calculated double scattering cross-section for a composite target

Abstract

In the effective action approach the imaginary part of the triple pomeron amplitude is calculated. The found dependence on the longitudinal momentum transfer $\e$ is found to separate as a simple factor $1/|\e|$. This result is used to calculate the high-mass diffraction on a hadron and double scattering cross-section off a composite target}
