Contribution

It introduces a model coupling chiral fermions to a dilaton background and shows unitarity preservation during black hole scattering, highlighting the role of anomalies.

Findings

Scattering preserves unitarity and information

Faddevian anomaly influences the information scenario

Chiral fermion scattering does not violate quantum principles

Abstract

A model where chiral boson is coupled to a background dilaton field is considered to study the s-wave scattering of fermion by a back ground dilaton black hole. It is found that the scattering process of chiral fermion does not violate unitarity and information remains preserved. Faddevian anomaly plays a crucial role on the information scenario.
