String scattering off the (2+1)-dimensional rotationg black hole

TL;DR

This paper investigates string scattering in a (2+1)-dimensional rotating black hole background, calculating the Hawking temperature through Bogoliubov transformations, contributing to understanding quantum effects in lower-dimensional black holes.

Contribution

It provides a detailed analysis of string scattering and Hawking radiation in the (2+1)-dimensional black hole modeled by the $SL(2, R)/Z$ WZW orbifold, a novel approach in this context.

Findings

Calculated the Hawking temperature for the rotating black hole.

Analyzed the $1 ightarrow 1$ tachyon scattering process.

Connected string scattering results with black hole thermodynamics.

Abstract

The $SL(2, R)/Z$ WZW orbifold describes the (2+1)-dimensional black hole which approaches anti-de~Sitter space asymptotically. We study the $1 \rightarrow 1$ tachyon scattering off the rotating black hole background and calculate the Hawking temperature using the Bogoliubov transformation.
