Dilepton emission at temperature dependent baryonic quark-gluon plasma

TL;DR

This paper investigates dilepton emission rates from a temperature-dependent baryonic quark-gluon plasma modeled with a statistical approach, highlighting how temperature and chemical potential influence emission spectra.

Contribution

It introduces a model incorporating temperature-dependent quark masses and chemical potential, providing new insights into dilepton production in QGP.

Findings

Dilepton emission rates increase with temperature-dependent chemical potential.

The spectrum in the intermediate mass region (1.0-4.0 GeV) shows a strong dependence on temperature.

Enhanced emission rates correlate with larger QGP droplets and higher quark masses.

Abstract

A fireball of QGP is evoluted at temperature dependent chemical potential by a statistical model in the pionic medium. We study the dilepton emission rate at temperature dependent chemical potential (TDCP) from such a fireball of QGP. In this model, we take the dynamical quark mass as a finite value dependence on temparature and parametrization factor of the QGP evolution. The temperature and factor in quark mass enhance in the growth of the droplets as well as in the dilepton emission rates. The emission rate from the plasma shows dilepton spectrum in the intermediate mass region (IMR) of (1.0-4.0) GeV and its rate is observed to be a strong increasing function of the temperature dependent chemical potential for quark and antiquark annihilation.
