Abstract
Dilepton emission is calculated from quark-gluon plasma (QGP) with the consideration of temperature dependent chemical potential (TDCP). The model is considered to be quasi-model and hence take the dynamical quark mass as a finite value dependence on temperature. The temperature in quark mass enhances in the growth of dilepton emission rates. The emission rate of dilepton spectrum is shown 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 anti-quark annihilation.

IntroductionBass et al [18] idea of parton rescattering and fragmentation leads to a substantial increase in the net-baryon density at midrapidity region
The ongoing experiments like ultra-relativistic heavy-ion collision at BNL and the large hadron collider at CERN have focused on the search of the QCD phase structure and the formation of mini big bang
In order to see the production of dilepton for the signal of quark-gluon plasma (QGP) formation, we look at the process of annihilation of quark and antiquark and they produce virtual photons which subsequently decay into dileptons such as l l
Summary
Bass et al [18] idea of parton rescattering and fragmentation leads to a substantial increase in the net-baryon density at midrapidity region. Besides these works, we have reports of other authors on dilepton production at low mass region [19,20,21]. These works suggest the importance of chemical potential in the dilepton calculation To produce such emission, we consider a QGP system in which the equilibrium thermodynamic of system is a function of temperature T and chemical potential and the potential itself as function of temperature. The paper is organized as follows: In Section II we look at the dilepton emission and integrated yields at temperature dependent chemical potential (TDCP).
