Description

Jet quenching parameter $\hat{q}$ is an essential parameter that characterizes the interaction strength between jet partons and the QGP. Based on the quark-meson model, we conduct a first calculation on $\hat{q}$ at finite chemical potential up to the one-loop order, and find that the momentum broadening of jets is enhanced not only at high temperature, but also at high chemical potential. We further investigate the behavior of $\hat{q}$ near the critical end point (CEP) of the QCD phase diagram by coupling our calculation with a recently developed equation of state that includes a CEP in the universality class of the Ising model.
