Parton Distributions in the Valon Model
Abstract
The parton distribution functions determined by CTEQ at low Q2 are used as inputs to test the validity of the valon model. The valon distributions in a nucleon are first found to be nearly Q independent. The parton distribution in a valon are shown to be consistent with being universal, independent of the valon type. The momentum fractions of the partons in the valon add up separately to one. These properties affirm the validity of the valon model. The various distributions are parameterized for convenient application of the model.
