Hawking radiation in Non local field theories

TL;DR

This paper investigates whether non-local quantum field theories alter Hawking radiation, concluding that Hawking radiation remains unchanged, thus demonstrating its universality beyond local theories.

Contribution

It proves that Hawking radiation is unaffected in a broad class of non-local quantum field theories, extending the understanding of its robustness.

Findings

Hawking radiation is unmodified in non-local theories

Universality of Hawking radiation is established

Locality is not essential for Hawking radiation

Abstract

Locality plays a key role in the derivation of Hawking radiation. Could relaxing the locality criterion modify Hawking radiation? We consider Hawking radiation in a general class of non local quantum field theories. We prove that Hawking radiation is unmodified for these theories. Our result establishes the universality of Hawking radiation in a larger class of theories.
