Drag force on a moving heavy quark with deformed string configuration

Abstract To study drag force on a moving heavy quark through plasma, we use deformed AdS space-time, in which deformation parameter c describes non-conformality AdS/QCD. In this case the is mapped to probe string space. Considering probable contribution of string, apply general form c-dependent ansatz computation. Then find acceptable value as it satisfies QCD calculations. Using result, also discuss diffusion constant agreement with phenomenological result for non-relativistic limit. Also show that while absence parameter, strictly increasing function radial coordinate, has maximum versus z.
