摘要

Recent research shows that Hawking radiation from black hole horizon can be treated as a quantumtunneling process, and fermions tunneling method can successfully recover Hawking temperature.In this tunnelingframework, choosing a set of appropriate matrices γ~μ is an important technique for fermions tunneling method.Inthis paper, motivated by Kerner and Man's fermions tunneling method of 4 dimension black holes, we further improvethe analysis to investigate Hawking tunneling radiation from a rotating charged black hole in 5-dimensional gaugedsupergravity by constructing a set of appropriate matrices γ~μ for general covariant Dirac equation.Finally, the expectedHawking temperature of the black hole is correctly recovered, which takes the same form as that obtained by othermethods.This method is universal, and can also be directly extend to the other different-type 5-dimensional chargedblack holes.
