Title Kinematical constraint effects in the evolution equations based on angular ordering Type Journal Article
Year 2015 Publication Journal of High Energy Physics Abbreviated Journal J. High Energy Phys.
Volume 05 Issue 5 Pages 068 - 13pp
Keywords (up) QCD Phenomenology; Deep Inelastic Scattering (Phenomenology)
Abstract We study effects of imposing various forms of the kinematical constraint on the full form of the CCFM equation and its non-linear extension. We find, that imposing the constraint in its complete form modifies significantly the shape of gluon density as compared to forms of the constraint used in numerical calculations and phenomenological applications. In particular the resulting gluon density is suppressed for large values of the hard scale related parameter and k(T) of gluon. This result might be important in description of jet correlations at Large Hadron Collider within the CCFM approach.

Title Nuclear medium modification of the F2(x, Q^2) structure function Type Journal Article
Year 2011 Publication Nuclear Physics A Abbreviated Journal Nucl. Phys. A
Volume 857 Issue 1 Pages 29-41
Keywords (up) Structure function; Nuclear medium effects; Deep inelastic scattering; Local density approximation
Abstract We study the nuclear effects in the electromagnetic structure function F-2(x, Q(2)) in the deep inelastic lepton nucleus scattering process by taking into account Fermi motion, binding, pion and rho meson cloud contributions. Calculations have been done in a local density approximation using relativistic nuclear spectral functions which include nucleon correlations. The ratios R-F2(A) (x, Q(2)) = 2F(2)(A)(x, Q(2))/AF(2)(D)(x, Q(2)) are obtained and compared with recent JLab results for light nuclei with special attention to the slope of the x distributions. This magnitude shows a non-trivial A dependence and it is insensitive to possible normalization uncertainties. The results have also been compared with some of the older experiments using intermediate mass nuclei.

Title Analysis of Nuclear Effects in Structure Functions and Their Connection with the Binding Energy of Nuclei Type Journal Article
Year 2023 Publication Brazilian Journal of Physics Abbreviated Journal Braz. J. Phys.
Volume 53 Issue 6 Pages 161 - 8pp
Keywords (up) Structure functions; Deep inelastic scattering; EMC effect; Nuclear dynamics
Abstract We describe nuclear effects in structure functions of nuclei in DIS by means of a multiplicative factor beta(A)(x) which differentiates the structure function of the bound nucleons from that of the free nucleons. Our analysis determines that beta(A)(x) establishes a relation between the quark-gluon dynamics expressed by the bound nucleon structure functions and the nuclear dynamics as described by the well-known semi-empirical Bethe-Weizsacker mass formula. This relation corroborates a connection between the underlying quark-gluon dynamics and the phenomenological nuclear dynamics.
