Abstract

By extending the statistical distributions to the transverse degree of freedom, we account for a multiplicative factor in the Fermi–Dirac functions of the light quarks, we were led to introduce in a previous work to comply with experiment. We can also get light antiquark distributions, similar to those we proposed earlier.
