GENERALIZED STATISTICS AND SOLAR NEUTRINOS

The generalized Tsallis statistics produces a distribution function ap propriate to describe the interior solar plasma, thought as a stellar polytrope, showing a tail depleted with respect to the Maxwell-Boltzma nn distribution and reduces to zero at energies greater than about 20k (B)T. The Tsallis statistics can theoretically support the distributio n suggested in the past by Clayton and collaborators, which shows also a depleted tail, to explain the solar neutrino counting rate.
