Glimpses on the micro black hole Planck phase

TL;DR

This paper investigates the late-stage properties of micro black holes near the Planck phase using generalized uncertainty principles, considering emissions of photons and gravitons within extra-dimensional models.

Contribution

It introduces a comparative analysis of micro black hole thermodynamics near the Planck phase using two different generalized uncertainty principles in extra-dimensional frameworks.

Findings

Mass thresholds and lifetimes are computed for micro black holes.

Entropy and heat capacity are analyzed near the Schwarzschild phase.

Emissions of photons and gravitons are incorporated into the models.

Abstract

Mass thresholds, lifetimes, entropy and heat capacity for micro black holes close to their late Schwarzschild phase are computed using two different generalized uncertainty principles, in the framework of models with extra spatial dimensions. Emissions of both photons and gravitons (in the bulk) are taken into account. Results are discussed and compared.
