Hawking radiation of massive vector particles from the linear dilaton black holes

Abstract

By using the tunneling formalism, we calculated the massive vector particles’ Hawking radiation from the non-rotating and rotating linear dilaton black holes. By applying the WKB approximation to the Proca field equation that govern the dynamics of massive vector bosons, we derive the tunneling probabilities and radiation spectrums of the emitted vector particles from the linear dilaton black holes. The Hawking temperatures of the linear dilaton black holes have been recovered, which are consistent with the previous results in the literature. This means that the vector particles’ tunneling method can also be used in studying the Hawking radiation of asymptotically non-flat and non-AdS black holes.
