Massive particles' Hawking radiation via tunneling from the G.H Dilaton black hole

TL;DR

This paper extends tunneling-based Hawking radiation analysis to massive particles from G.H Dilaton black holes, demonstrating consistent emission rates and functional forms with massless cases, supporting unitarity.

Contribution

It introduces a method to analyze massive particle tunneling from G.H Dilaton black holes, expanding previous work on massless particles and confirming theoretical consistency.

Findings

Massive particles tunnel with emission rates similar to massless particles.

The tunneling process is consistent with an underlying unitary theory.

The functional form of emission rate remains unchanged for massive particles.

Abstract

In the past, Hawking radiation was viewed as a tunneling process and the barrier was just created by the outgoing particle itself. In this paper, Parikh's recent work is extended to the case of massive particles' tunneling. We investigate the behavior of the tunneling massive particles from a particular black hole solution-G.H Dilaton black hole which is obtained from the string theory, and calculate the emission rate at which massive particles tunnel across the event horizon. We obtain that the result is also consistent with an underlying unitary theory. Furthermore, the result takes the same functional form as that of massless particles.
