Two-Photon Correlations in $pp$ Collisions

TL;DR

This paper investigates two-photon correlations in proton-proton collisions to extract space-time information about the Higgs-boson source and estimates its mass in a thermal environment.

Contribution

It introduces a novel method to analyze two-photon correlations for Higgs-boson source characterization and provides the first estimate of the Higgs-boson mass using this approach.

Findings

Two-photon correlation functions reveal space-time properties of the Higgs source.

First estimation of Higgs-boson mass from photon correlation data.

Abstract

It is well understood that the studies of correlations between produced particles, the effects of coherence and chaoticity, an estimation of particle emitting source size play an important role in high energy physics [1]. First of all, we mean the investigation of the space-time extension or even squeezing of particle sources via the multiparticle quantum-statistics correlation. We consider the two-photon correlation function that can provide the space-time information about the Higgs-boson source in thermal environment and estimate the Higgs-boson mass for the first time.
