Cavitation and thermal dilepton production in QGP

Understand

We study the \textit{non-ideal} effects arising due to viscosity (both bulk and shear), equation of state ($\epsilon\neq 3P$) 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.
