There Is No Proof of Thermalized Quark-Gluon Plasma at RHIC and LHC

TL;DR

This paper argues that there is no definitive proof of thermalized quark-gluon plasma at RHIC and LHC because the experimental data are not compared with exact first-principle calculations, unlike other particle discoveries.

Contribution

It highlights the need for nonequilibrium-nonperturbative QCD as the exact first-principle method to study QGP at RHIC and LHC, challenging existing interpretations.

Findings

No conclusive evidence of thermalized QGP at RHIC and LHC.

Current experimental data rely on simplistic models, not first-principle calculations.

Proposes nonequilibrium-nonperturbative QCD as the proper approach.

Abstract

Although Tevatron has discovered top quark and LHC (pp collisions) has discovered Higgs boson but the RHIC and LHC heavy-ion colliders have not discovered thermalized quark-gluon plasma (QGP). This is because the experimental data of top quark at Tevatron and the experimental data of Higgs boson at LHC are compared with the exact first principle calculation but the experimental data at RHIC and LHC are compared with simplistic models and assumptions which are not exact first principle calculation. In this paper we show that the exact first principle method to study quark-gluon plasma at RHIC and LHC is the nonequilibrium-nonperturbative QCD by using closed-time path integral formalism. Hence in the absence of such exact first principle calculation we conclude that there is no proof of thermalized quark-gluon plasma at RHIC and LHC.
