The Scattering of Strings in a Black-Hole Background

TL;DR

This paper investigates tachyon correlation functions in a two-dimensional black-hole background, demonstrating consistency with predictions from a deformed matrix model, thus linking string scattering and matrix models.

Contribution

It provides the first detailed analysis of string scattering in a black-hole background and confirms the deformed matrix model's predictions.

Findings

Correlation functions match matrix model predictions

Supports the use of matrix models for black-hole string dynamics

Enhances understanding of string behavior in curved spacetime

Abstract

In this paper, correlation functions of tachyons in the two-dimensional black-hole are studied. The results are shown to be consistent with the prediction of the deformed matrix model.
