Description

Heavy-ion collisions have been used to study quark-gluon plasma (QGP)
and can be used to study strong electromagnetic (EM) fields. Because the
EM fields penetrate the QGP medium, their evolutions are coupled
together. In turn, both contribute to the production of photons [1, 2].
Usually, the EM field modifications are considered separately from the
evolution of the QGP. Instead, we model the dynamic evolution of the QGP
and EM fields together using relativistic resistive
magneto-hydrodynamics (RRMHD) [2]. Our RRMHD model is unique for
heavy-ion collisions because it includes a finite scalar electrical
conductivity. That conductivity acts as a dissipative correction in the
distribution function of QGP, similar to viscosity. This alters the
yield and flow of photons, and results in energy loss for jets. We will
give a detailed discussion on how our RRMHD model is connected to the EM
dissipative corrections of QGP. Also, we will introduce some possible
methods to study the electrical conductivity of QGP.
