TL;DR

This paper discovers deformed conformal symmetry generators for Kerr-Newman-NUT-AdS black holes, extending known symmetries, and supports the Kerr/CFT correspondence through scalar probe absorption cross-section analysis.

Contribution

It introduces a generalized framework of deformed conformal generators for these black holes, extending previous conformal symmetry models and linking to Reissner-Nordstrom-NUT-AdS solutions.

Findings

Extended local SL(2,R)_L imes SL(2,R)_R symmetries parameterized by deformation.

Derived absorption cross-section supporting Kerr/CFT correspondence.

Provided deformed generators applicable to non-rotating Reissner-Nordstrom-NUT-AdS black holes.

Abstract

We find generators of the conformal symmetry for the class of Kerr-Newman-NUT-AdS black holes from the deformed scalar probe equation. We find two classes of solutions for the generators (also known as conformal J and Q pictures). The two classes of deformed generators are the extension of similar generators for the regular conformal symmetry. Moreover, we find that the two pictures can be generalized and extended into a general picture. In each picture, the generators produce an extended local family of SL(2,R)_L \times SL(2,R)_R hidden conformal symmetries for the Kerr-Newman-NUT-AdS black holes which are parameterized by one deformation parameter. We find the absorption cross-section of the scalar probes for the Kerr-Newman-NUT-AdS black holes, which in turn, supports the existence of Kerr/CFT correspondence. Moreover, our deformed conformal generators for the Kerr-Newman-NUT-AdS black holes provide the deformed conformal generators for the non-rotating Reissner-Nordstrom-NUT-AdS black holes.
