Searching for new physics with three-particle correlations in $pp$ collisions at the LHC

TL;DR

This paper investigates three-particle correlations in proton-proton collisions at the LHC to identify potential signatures of new physics beyond the Standard Model, using a correlated-cluster model to interpret the data.

Contribution

It introduces a method to detect hidden sectors through three-particle correlations, extending the correlated-cluster model to include potential new physics effects.

Findings

Potential signature of new physics identified in three-particle correlations

Correlated-cluster model effectively describes multiparticle production

Experimental tests can directly verify the predicted effects

Abstract

New phenomena involving pseudorapidity and azimuthal correlations among final state particles in $pp$ collisions at the LHC can hint at the existence of hidden sectors beyond the Standard Model. In this paper we rely on a correlated-cluster picture of multiparticle production, which was shown to account for the ridge effect, to assess the effect of a hidden sector on three-particle correlations concluding that there is a potential signature of new physics that can be directly tested by experiments using well-known techniques.
