| dc.description.abstract | We obtain a simultanously fit to the nucleon experimental data of the flavor asymmetry d-/ū in the sea, and the ratio d/u. We use a statistical thermal model, where the quarks are confined inside the nucleon by a linear potential. We adjust the Gottfried sum rule violation with a temperature parameter. To obtain a good fit to the ratio d-/ū it was also included the contribution of gluon splitting processes. | en |
