Cavitation and thermal dilepton production in QGP
arXiv:1101.5597 · doi:10.1016/j.nuclphysa.2011.11.012
Abstract
We study the \textit{non-ideal} effects arising due to viscosity (both bulk and shear), equation of state () and cavitation on thermal dilepton production from QGP at RHIC energies. We calculate the first order corrections to the dilepton production rates due to shear and bulk viscosities. Ignoring the cavitation can lead to a wrong estimation of dilepton spectra. We show that the shear viscosity can enhance the thermal dilepton spectra whereas the bulk viscosity can suppress it. We present the combined effect of bulk and shear viscosities on the dilepton spectra.
