Abstract
Proc. of DIS 2012, 447-452; DESY
The phenomenological motivations, the expressions and the comparison
with experiment of the parton distributions inspired by the quantum
statistics are described. The Fermi-Dirac expressions for the quarks
and their antiparticles automatically account for the correlation
between the shape and the first moments of the valence partons, as
well as the flavor and spin asymmetries of the sea. One is able to
describe with a small number of parameters both unpolarized and polarized
structure functions.
