Heavy quark collisional energy loss in the quark-gluon plasma including finite relaxation time
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...

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.

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.
