We review a recent black hole particle production analisys in a regular spacetime metric obtained in a minisuperspace approach to loop quantum gravity. Repeating the Hawking analysis, which leads to a thermal flux of particles at the future infinity, one finds an infinite evaporation time and unitarity recovered due to the regularity of the singularity free spacetime and to the characteristic behavior of the surface gravity.

Abstract
We review a recent black hole particle production analisys in a regular spacetime metric obtained in a minisuperspace approach to loop quantum gravity. Repeating the Hawking analysis, which leads to a thermal flux of particles at the future infinity, one finds an infinite evaporation time and unitarity recovered due to the regularity of the singularity free spacetime and to the characteristic behavior of the surface gravity.File in questo prodotto:
