| The exact decay rate for emission of massless minimally coupled scalar fields by a non-extremal black hole in 2 + 1 dimensions is obtained. At low energy, the decay rate into scalars with zero angular momentum is correctly reproduced within conformal field theory. The conformal field theory has both left- and rightmoving sectors and their contribution to the decay rate is associated naturally with left and right temperatures of the black hole.

Extremal black holes often correspond to BPS-states of an underlying fundamental string theory. Agreement between the Bekenstein-Hawking entropy and the counting of string states for extremal black holes in five dimensions was first obtained in [1]. However, the correspon... | |||||||||||||||
