1. The polarized structure function from the nonextensive statistics.

Author

Trevisan, Luis Augusto

Subjects
*SYMMETRY, *FERMI-Dirac distribution, *THERMODYNAMICS, *BOLTZMANN'S constant, *QUARKS
Abstract

In the present work, the effects of the nonextensivity are considered in a model to obtain the polarized structure function for the proton and neutron, including the strange contribution for each one. Any type of symmetry is made in consequence of the experimental data involved. [ABSTRACT FROM AUTHOR]

Abstract

We studied an application of nonextensive thermodynamics to describe the structure function of nucleon, in a model where the usual Fermi-Dirac and Bose-Einstein energy distribution were replaced by the equivalent functions of the q-statistical. The parameters of the model are given by an effective temperature T, the q parameter (from Tsallis statistics), and two chemical potentials given by the corresponding up (u) and down (d) quark normalizations in the nucleon.
