Hawking Radiation as Tunneling from Garfinkle-Horowitz-Stromingen Dilaton Black Hole.

Applying quantum tunneling method, this paper has studied the Hawking radiation of Garfinkle-Horowitz-Stromingen dilaton black hole. In this way, the emission rates of massless particles and massive particles tunneling across the event horizon of black holes is obtained. The result shows that the radiation spectrum of these two different kinds of outgoing particles is related to the change of Bekenstein-Hawking entropy, which is no longer precisely thermal.
