Pomeron-Odderon interference in production of pi^ + pi^- pairs in ultraperipheral collisions

TL;DR

This paper explores how charge asymmetries in the production of two pion pairs during high-energy photon collisions in ultraperipheral hadron collider events can serve as evidence for the perturbative Odderon, a theoretical QCD construct.

Contribution

It introduces a method to detect the perturbative Odderon through charge asymmetries in pion pair production in ultraperipheral collisions.

Findings

Charge asymmetries can indicate the presence of the perturbative Odderon.

Ultraperipheral collisions at Tevatron, RHIC, and LHC are suitable for this study.

The proposed method could provide experimental evidence for the Odderon.

Abstract

In this contribution we discuss the production of two pion pairs in high energy photon collisions as they can be produced in ultraperipheral collisions at hadron colliders such as the Tevatron, RHIC or LHC. We find that charge asymmetries may reveal the existence of the perturbative Odderon.
