TL;DR

This paper investigates Hawking radiation as tunneling of charged fermions from charged, accelerating, rotating black holes with NUT parameter, analyzing tunneling probabilities and Hawking temperature using semiclassical methods.

Contribution

It extends previous studies by including the NUT parameter in the analysis of fermion tunneling from complex black hole spacetimes.

Findings

Tunneling probabilities are computed using WKB approximation.

Hawking temperature is derived for the black hole with NUT parameter.

Results reduce to known cases when NUT parameter is zero.

Abstract

This paper is devoted to the study of Hawking radiation as a tunneling of charged fermions through event horizons of a pair of charged accelerating and rotating black holes with NUT parameter. We evaluate tunneling probabilities of outgoing charged particles by using the semiclassical WKB approximation to the general covariant Dirac equation. The Hawking temperature corresponding to this pair of black holes is also investigated. For the zero NUT parameter, we find results consistent with those already available in the literature.
