Can Virtual Cosmic Strings Shift the Hawking Temperature?

TL;DR

This paper investigates whether virtual cosmic strings near a Schwarzschild black hole can alter the Hawking temperature, concluding that such strings do not produce measurable deviations in Hawking radiation.

Contribution

It demonstrates that virtual cosmic strings do not significantly affect the Hawking radiation emitted by black holes.

Findings

No detectable change in Hawking radiation due to virtual cosmic strings

Virtual cosmic strings do not alter black hole temperature in the studied scenario

Supports previous claims that cosmic strings have negligible impact on black hole thermodynamics

Abstract

The amount of the Hawking radiation in Hartle-Hawking vacuum around the Schwarzschild black hole is calculated in the presence of the cloud of virtual-cosmic-string loops near the black hole. Recently, Coleman, Preskill and Wilczek have discussed the black-hole temperature in such situation. We show, in this letter, it is hardly possible to find any deviation in the Hawking radiation even if the virtual cosmic strings exist.
