Abstract:

In this paper, we calculate the soft-collisional energy loss of heavy quarks traversing the viscous quark-gluon plasma including the effects of a finite relaxation time τπ on the energy loss. We find that the collisional energy loss depends appreciably on τπ. In particular, for typical values of the viscosity-to-entropy ratio, we show that the energy loss obtained using τπ≠0 can be ∼10% larger than the one obtained using τπ=0. Moreover, we find that the energy loss obtained using the kinetic theory expression for τπ is much larger than the one obtained with the τπ derived from the anti-de Sitter/conformal field theory correspondence. Our results may be relevant in the modeling of heavy quark evolution through the quark-gluon plasma. © 2014 American Physical Society.
