Abstract

It is argued that, using the black hole area entropy law together with the Boltzmann-Gibbs statistical mechanics and the quasinormal modes of the black holes, it is possible to determine univocally the lowest possible value for the spin jj in the context of the Loop Quantum Gravity theory which is jmin=1j_{min}=1. Consequently, the value of Immirzi parameter is given by γ=ln3/(2π2)\gamma = \ln 3/(2\pi\sqrt{2}). In this paper, we have shown that if we use Tsallis microcanonical entropy rather than Boltzmann-Gibbs framework then the minimum value of the label jj depends on the nonextensive qq-parameter and may have values other than jmin=1j_{min}=1.
