“…However, if the asymptotic predictions of Ref [1][2][3][4][5][6] are considered to be the rough indicator even for partial momentum fractions for small x quarks at the finite Q 2 , then the present result favors the prediction of Ref [5], instead of Ref [1][2][3][4], without violating the experimental value [30].…”

The paper reports analysis of momentum fractions carried by quarks and gluons in models of Proton structure functions at small x. First, we analyze the model proposed by Lastovicka based on self-similarity sometime back. We then make a similar analysis for a second model based on the same notion which is also free from singularity in x : 0 < x < 1. The predictions of both the models are then compared with a recent QCD based Froissart bound compatible model of proton structure function at small x, suggested by Block, Durand, Ha and McKay. The results are then compared with the corresponding study in perturbative and Lattice QCD.

“…The experimental results on the Q2 dependence of FA/F~ are often presented in terms of the logarithmic slopes d(FA/F~)/d(InQ2). These slopes have been found to be typically less than 0.05 (for Q2 expressed in GeV 2) and consistent with zero [1][2][3][4][5].…”

“…The observed results can be described in the framework of different models [1]. For x > 0.1, modifications of the nucleon characteristics inside a nucleus have been invoked; among them a reduced effective nucleon mass or an increase of the nucleon size.…”

The Q2 dependence of the structure function ratio FS"/lff for 0.01 < x < 0.75 and 1 < Q2 < 140 GeV 2 is reported. For x < 0.1 the size of shadowing decreases linearly with lnQ 2 and the maximum rate is about 0.04 at x = 0.01. The rate decreases with x and is compatible with zero for x/> 0.1. The difference R sn -R c, where R is the ratio of longitudinally to transversely polarised virtual photon absorption cross sections, is also given. No dependence on x is seen and the average value is 0.0404-0.021 (stat.) 4-0.026 (syst.) at a mean Q2 of 10 GeV 2.

“…dxx(x) = 1 (52) if quarks and antiquarks carry all of the momentum of the nucleon. This was not conrmed, the experimental measurement of 0:5 implied that there was more momentum in the nucleon than that carried by the quarks and antiquarks and gave impetus to the development of the theory of QCD, in which the decit in momentum is carried by the gluons.…”

The current status of measurements of the nucleon structure functions and their understanding is reviewed. The xed target experiments E665, CCFR and NMC and the HERA experiments H1 and ZEUS are discussed in some detail. The extraction of parton momentum distribution functions from global ts is described, with particular attention paid to much improved information on the gluon momentum distribution. The status of s measurements from deep inelastic data is reviewed. Models and non-perturbative approaches for the parton input distributions are outlined. The impact on the phenomenology of QCD of the data at very low v alues of the Bjorken x variable is discussed in detail. Recent advances in the understanding of the transition from deep inelastic scattering to photoproduction are summarized. Some brief comments are made on the recent HERA measurements of the ep NC and CC cross-sections at very high Q 2 .
