“…The result is compared with the earlier results of Ref. [23,24,27]. So the model with the temperature and chemical potential dependent on quark mass gives better outputs and agrees well with the recent theoretical results in dilepton emission.…”

“…Here we exclusively use qq → l + l − reaction as our choice because of its higher production of intermediate mass of dilepton pair in these reactions. In the calculation we use approximated Fermi-Dirac distribution function for quarks and antiquarks with their corresponding parton fugacities λ q(q) = e µ/T [27]. They are defined as:…”

We extend to study the dilepton emission from heavy-ion collision of quark gluon plasma incorporating the temperature and chemical potential dependent on quark mass. The dilepton emission rate is found to be enhanced in comparison to the earlier calculation of dilepton emission from temperature dependent quark mass and to other theoretical calculations. The study finds that the emission rate of dilepton through the chemical potential is increasing function depending on the increasing value of chemical potential ranging from µ = 0.10 − 0.40 GeV. This indicates that the overall result of dilepton emission through both chemical potential and temperature provide better information about the signature of forming quark-gluon plasma.

We extend to calculate the direct photon production from quark–gluon plasma (QGP) considering finite chemical potential. The calculation is done from a system of strongly interacting QGP and the result is found to be increasing function of chemical potential in all the channels of photon production. It also shows enhancement of photon production from photon production without chemical potential and other theoretical calculation of direct photon productions.

Hard photons emitted from energetic heavy-ion collisions are very interesting since they do not experience nuclear interaction, and therefore they are useful to explore properties of nuclear matter. We investigated hard-photon production and its properties in intermediate-energy heavy-ion collisions with the help of the Blotzmann-Uehling-Ulenbeck model. Two components of hard photons are discussed: direct and thermal. The positive directed flow parameter and negative elliptic flow parameter of direct photons are demonstrated and they are anticorrelated to the flows of free protons. The dependencies of hard-photon production and anisotropic parameters on impact parameter, beam energy, nuclear equation of state, and symmetry energy are also discussed. Furthermore, we investigated the two-photon momentum correlation function, from which the space-time structure information of the photon source could be extracted, as well as the two-photon azimuthal correlation, which could provide another good method to determine the elliptic flow parameter v 2 of direct hard photons.
