The Hawking radiation of the charged particle via tunnelling from the axisymmetric Sen black hole

Extending Parikh's semi-classical quantum tunnelling model, this paper has studiedthe Hawking radiation of the charged particle via tunnelling from the horizon of theaxisymmetric Sen black hole. Different from the uncharged massless particle, thegeodesics of the charged massive particle tunnelling from the horizon is notlight-like. The derived result supports Parikh's opinion and provides a correctmodification to Hawking strictly thermal spectrum developed by the fixed backgroundspace-time and not considering the energy conservation and the self-gravitationinteraction.
