Vaidya-de Sitter Black Hole with Spin Fields
-
Abstract
The generalized Teukolsky-type master equation in Vaidya-de Sitter space-time is given. It is found that the massive Dirac field of spin state p = 1/2 differs greatly from the massive Dirac field of spin state p =-1/2 in radiative mechanism. This effect originates from the variance of Dirac vacuum near the event horizon in the nonstatic space-time caused by spin state. -
