In this paper, we report an analysis of partial momentum fractions carried by quarks and gluons in six alternative phenomenological models of proton structure function valid in limited small x regions: xai ≤ x ≤ xbi, i = 1 to 6; the limits being determined by phenomenological range of validity in each model. Since the physics of small x is not completely understood at this point, we have considered both self-similarity-based as well as QCD-based models. The procedure by which one can determine t...

Froissart Bound implies that the total proton-proton cross-section (or equivalently structure function) cannot rise faster than the logarithmic growth \log^2 s \sim \log^2 1/x where \textit{s} is the square of the center of mass energy and \textit{x} is the Bjorken variable. Compatibility of such behavior with the notion of self-similarity in a model of structure function suggested by us sometime back is now generalized to more recent improved self-similarity based models and compare with rec...

Sometime back, a self-similarity based model of the proton structure function at small x was proposed by Lastovicka. We make reanalysis of this model with most recent HERA data. No significance difference with the earlier analysis is found. Both the analyses have singularity within the kinematical range of x: 0 ≤ x ≤ 1. We therefore study the model with the additional assumption that it should be singularity free, imposing positivity conditions on the model parameters. This results in a new mode...
