Scaling quark gluon plasma by HBT interferometry with lepton pairs

TL;DR

This paper investigates how HBT interferometry with lepton pairs can be used to measure the size and lifetime of the quark-gluon plasma in nuclear collisions at RHIC and LHC, revealing differences in radial flow.

Contribution

It introduces the use of invariant mass dependence of HBT radii from dilepton correlations as a novel scaling method for quark-gluon plasma properties.

Findings

Different magnitudes of HBT radii at RHIC and LHC

Stronger radial flow observed at LHC

HBT radii can effectively scale plasma size and lifetime

Abstract

We study the intensity interferometry with lepton pairs for nuclear collisions at RHIC and LHC energies. It is argued that the invariant mass dependence of HBT radii extracted from the correlation functions of dilepton pairs can be used as an efficient tool to scale the size and life time of the quark gluon plasma expected to be formed in nuclear collisions at RHIC and LHC. Quantitatively different magnitudes of HBT radii are obtained at RHIC and LHC indicating stronger radial flow at LHC.
