Patterns of the Exclusive Double Diffraction

TL;DR

This paper analyzes Exclusive Double Diffractive Events (EDDE) in proton-proton interactions, providing cross-section calculations and proposing measurements to extract detailed information about the interaction region from diffractive patterns.

Contribution

It offers a new calculation framework for EDDE cross-sections and suggests experimental measurements to probe the interaction region more precisely.

Findings

Cross-section formulas for $p+p o p+M+p$ are derived.

Diffractive patterns can reveal the structure of the interaction region.

Proposes joint CMS-TOTEM measurements for experimental validation.

Abstract

We consider Exclusive Double Diffractive Events (EDDE) as a powerfull tool to study the picture of the $pp$ interaction. Calculations of the cross-sections for the process $p+p\to p+M+p$ are presented in the convenient form for further experimental applications. We propose measurements of t-distributions in the joint CMS-TOTEM experiment. It is shown that important information on the interaction region could be extracted from the diffractive pattern.
