Statistical Model for the Nucleon Structure Functions
A phenomenological model for the nucleon structure functions is presented. Visualising the nucleon as a cavity filled with parton gas in equilibrium and parametrizing the effects due to the finiteness of the nucleon volume, we obtain a good fit to the data on the structure function F p 2 . The model then successfully predicts other unpolarized structure function data. PACS: 13.60.Hb, 12.40.Ee

A phenomenological model for the nucleon structure functions is presented. Visualising the nucleon as a cavity filled with parton gas in thermal equilibrium and parametrizing the effects due to the finiteness of the nucleon volume, we obtain a good fit to the data on the unpolarized nucleon structure functions. 13.60.Hb, 12.40.Ee Typeset using REVTEX 1 Recent experiments have revealed some rema...
متن کاملNucleon Structure Functions
New structure function measurements from fixed target experiments and especially HERA are reviewed. The extraction of parton distributions from these measurements is discussed with special emphasis on systematic problems. New information from Drell-Yan and direct photon production experiments are also presented . Finally the present uncertainties of our knowledge on parton distributions and on ...
متن کاملNucleon Structure Functions in the Three Flavor NJL Soliton Model ∗
We study the relevance of strange degrees of freedom for nucleon structure functions. For this purpose we employ the three flavor generalization of the collective quanti-zation approach to the chiral soliton of the bosonized Nambu–Jona–Lasinio model. Contrary to many other soliton models the hadronic tensor is tractable in this model. By applying the Bjorken limit to the hadronic tensor we extr...
متن کاملChiral Symmetry and the Nucleon Structure Functions
The flavor asymmetry of the sea quark distribution as well as the unexpectedly small quark spin fraction of the nucleon are two outstanding discoveries recently made in the physics of deep-inelastic structure functions. We evaluate here the corresponding quark distribution functions within the framework of the chiral quark soliton model, which is an effective quark model of baryons maximally in...
