An approximated solution for the gluon distribution from DGLAP evolution equations with the NLO splitting function in the small-x limit is *** first obtain simplified forms of the LO and NLO splitting functions in the small-x *** these approximated splitting functions,we obtain the analytical gluon distribution using the Mellin *** free parameters in the boundary conditions are obtained by fitting the CJ15 gluon distribution *** find that the asymptotic behavior of the gluon distribution is consistent with the CJ15 data;however,the NLO results considering the"ladder"structure of gluon emission are slightly better than the LO *** results indicate that the corrections from NLO have a significant influence on the behavior of the gluon distribution in the small-x *** addition,we investigate the DGLAP evolution of the proton structure function using the analytical solution of the gluon *** differential structure function reveals that our results have a similar tendency to the CJ15 data at small-x.

Longitudinal Structure Function FL from Charm Structure Function F2^c

引用

Communications in Theoretical Physics 2013年第4期59卷 462-466页

作者： B. Rezaei G.R. Boroun Physics Department Razi University

We predict the effect of the charm structure function on the longitudinal structure function at small x. In NLO analysis we find that the hard Pomeron behavior gives a good description of FL and Fk^c （k = 2, L） at small x values. We conclude that a direct relation between FL∝ F2^c would provide useful information on how to measure longitudinal structure function at high 0,2 values. Having checked that this model gives a good description of the data, when compared with other models.

In this paper,the proton structure function F_(2)^(p)(x,Q^(2))at small-x is investigated using an analytical solution to the Balitsky–Kovchegov(BK)*** the context of the color dipole description of deep inelastic scattering(DIS),the structure function F_(2)^(p)(x,Q^(2))is computed by applying the analytical expression for the scattering amplitude N(k,Y)derived from the BK *** transverse momentum k and total rapidity Y,the scattering amplitude N(k,Y)represents the propagation of the quark-antiquark dipole in the color dipole description of *** the BK solution we extracted the integrated gluon density xg(x,Q^(2))and then compared our theoretical estimation with the LHAPDF global data fits,NNPDF3.1sx and ***,we have investigated the behavior of F_(2)^(p)(x,Q^(2))in the kinematic region of 10^(-5)≤x≤10^(-2)and 2.5 GeV^(2)≤Q^(2)≤60 GeV^(2).Our predicted results for F_(2)^(p)(x,Q^(2))within the specified kinematic region are in good agreement with the recent high-precision data for F_(2)^(p)(x,Q^(2))from HERA(H1 Collaboration)and the LHAPDF global parametrization group NNPDF3.1sx.
