Early Universe Test of Nonextensive Statistics

arXiv:astro-ph/9705068 · doi:10.1103/PhysRevLett.79.1588

Abstract

Within an early Universe scenario, nonextensive thermostatistics (NET) is investigated on the basis of data concerning primordial Helium abundance. We obtain first order corrections to the energy densities and weak interactions rates, and use them to compute the deviation in the primordial Helium abundance. After compare with observational results, a severe bound is stablished.
