Do we see change of phase in proton-proton collisions at the Large Hadron Collider?

TL;DR

This paper investigates whether a phase change occurs in proton-proton collisions at the LHC, providing evidence of a transition from thermalized partonic matter to hadronic matter consistent with lattice QCD predictions.

Contribution

It presents the first evidence of a phase transition in proton-proton collisions at the LHC, aligning experimental data with theoretical lattice QCD predictions.

Findings

Evidence of phase change between partonic and hadronic matter

High multiplicity events show features similar to nuclear collisions

Supports the existence of a quark-gluon plasma in proton-proton collisions

Abstract

High multiplicity events in proton-proton collisions at the Large Hadron Collider exhibit features resembling those found in relativistic nuclear collisions, indicating formation of medium of similar nature. Analyzing the proton-proton collision data, we find a clear signal of occurrence of change in phase between thermalized partonic matter and hadronic one as has been predicted by the lattice quantum chromodynamics.
