The massive and charged particle radiation from arbitrary dimensional Horowitz-Strominger dilaton black hole

When the black hole radiates particles, its mass decreases and the horizon contracts, the space-time geometry is dynamical. The separation between the initial and final radius of the horizon forms the barrier for tunnelling. This paper promotes the work of Parikh and Wilczek [M.K. Parikh, F. Wilczek, Phys. Rev. Lett. 85 (2000) 5042; M.K. Parikh, Gen. Relativ. Gravit. 36 (2004) 2419] to the radiation of the massive, charged particles from arbitrary dimensional Horowitz-Strominger black hole. We get that the tunnelling rate equals precisely the exponent of the difference of the black hole entropy before and after emission, just like the radiation of massless particles. The result supports the viewpoint of information conservation.
