Abstract
We analyze physical observables of heavy quarks in gravity models describing strongly coupled non-conformal plasmas with anisotropy via the gauge/gravity duality. The focus lies on the binding energy of static quark-antiquark (\( q\overline{q} \)-)pairs, the maximum distance (screening distance) of a bound \( q\overline{q} \)-pair and the drag force on uniformly moving quarks in the hot plasma. In order to discover universal behavior in the observables, the computations are worked out in a two parameter deformation of pure gravity in AdS5 spacetime with a black brane which is assumed to be dual to a respective two parameter deformation of \( \mathcal{N} \) = 4 supersymmetric Yang-Mills (SYM) theory at temperature T. The deformation is designed to break isotropy and conformal symmetry and is a solution to equations of motion of a gravity action.
