On black hole radiation spectrum in loop quantum gravity

Abstract

We propose an alternative analysis of black hole entropy from loop quantum gravity (LQG) to reconcile Hawking’s semiclassical results with the statistical mechanics treatment of LQG for all values of the Barbero-Immirzi (BI) parameter. In particular, using the average area of the punctures, we have calculated the corresponding entropy, identified the BI parameter and derived the radiation spectrum in terms of the possible punctures.
