Chromo-turbulent fields and lepton pair production from collisional hot QCD medium

We investigate the effects of collisional processes in the hot QCD medium to thermal dilepton production from qq¯ annihilation in relativistic heavy-ion collisions. The non-equilibrium corrections to the momentum distribution function have been estimated within the framework of ensemble-averaged diffusive Vlasov–Boltzmann equation, encoding the effects of collisional processes and turbulent chromo-fields in the medium. The analysis has been done by employing a quasiparticle model for the thermal QCD medium which incorporates the realistic equation of state. We have shown that the collisional corrections have a significant impact on the thermal dilepton spectra.
