In this paper, we consider rotating black hole in three dimensions with a scalar charge and discuss about the jet-quenching parameter. We find that the effect of scalar charge is decreasing and rotation parameter is increasing the value of the jet-quenching parameter.
In this paper, we consider a charged black hole in three dimensions with a scalar charge and discuss energy loss of a heavy particle moving near the black hole horizon. This analysis is useful when anti-de Sitter space – conformal field theory correspondence is applied. We find that an electric charge of a black hole increases the drag force but a scalar charge decreases it.
