Tunnelling of Massive Vector Particles from Dilaton Black Holes in (2+1)Dimensions

[摘要] In this paper, we have studied the Hawking radiation of massive spin-1 particles from the black holes in (2+1) dimensions with non-trivial dilaton fields. We consider two special varieties of these black holes one is static charged and other is spinning electrically neutral. By applying the standard method of WKB approximation and Hamilton-Jacobi ansatz we have shown the tunnelling probability and Hawking temperature of massive bosons accordingly. In the certain limit of the dilaton coupling for spinning neutral case we have recovered the Hawking temperature of the BTZ black holes as well.
