Odderon: models vs experimental data - a short review of recent papers

TL;DR

This review examines recent theoretical and experimental studies on the Odderon, focusing on debates over its discovery and interpretations following the low $ ho_{pp}$ measurement at 13 TeV.

Contribution

It provides a comparative analysis of recent papers that challenge the claim of Odderon discovery based on the TOTEM data.

Findings

Some recent papers contest the Odderon discovery

Debates focus on interpretation of $ ho_{pp}$ data

The review highlights differing theoretical models

Abstract

The surprising low TOTEM datum $\rho_{pp}$ = 0.09$\pm$0.01 at 13 TeV \cite{TOTEM-1} generated an important flux of papers, which can be classified in three categories: 1) papers which claim that this result is the first experimental discovery of the Odderon, namely in its maximal form; 2) papers which tried, without success, to find alternative explanations of this result; 3) papers which contest the discovery of the Maximal Odderon. In the present short note we discuss two recent papers belonging to the third category.
