Two-Form Fields and the Gauge Theory Description of Black Holes

TL;DR

This paper investigates how two-form field perturbations interact with black threebranes, revealing suppressed Hawking radiation at low energies and connecting it to gauge theory operators.

Contribution

It provides a detailed calculation of absorption cross sections for two-form perturbations and decouples coupled equations for s-wave modes, linking gravitational and gauge theory behaviors.

Findings

Hawking rate is suppressed at low energies.

Coupling to a higher dimension operator in gauge theory.

Decoupling of coupled equations for s-wave perturbations.

Abstract

We calculate the absorption cross section on a black threebrane of two-form perturbations polarized along the brane. The equations are coupled and we decouple them for s-wave perturbations. The Hawking rate is suppressed at low energies, and this is shown to be reflected in the gauge theory by a coupling to a higher dimension operator.
