S-Wave Scattering of Fermion revisited taking into account the effect of Anomaly

TL;DR

This paper investigates how anomalies influence s-wave fermion scattering in a dilaton black hole background, revealing their dual role in either preventing or contributing to information loss.

Contribution

It introduces a model considering anomaly effects in fermion scattering by dilaton black holes, highlighting their complex impact on information loss scenarios.

Findings

Anomalies can both protect and threaten information preservation.

The dual role of anomalies depends on specific scattering conditions.

The study advances understanding of quantum effects in black hole physics.

Abstract

A model where a Dirac fermion is coupled to background dilaton field is considered to study s-wave scattering of fermion by a background dilaton black hole. It is found that the anomaly plays a dual role on information loss scenario. Some time it protects the fermion from the dangerous information loss problem and some times it itself through it up towards that danger.
