Heavy-quark contributions to the ratio F_L/F_2 at low x
Alexey Yu. Illarionov, Bernd A. Kniehl, Anatoly V. Kotikov
We study the heavy-quark contribution to the proton structure functions F_2^i(x,Q^2) and F_L^i(x,Q^2), with i=c,b, for small values of Bjorken's x variable at next-to-lading order…
Critical tests of unintegrated gluon distributions
H. Jung, A. V. Kotikov, A. V. Lipatov +1
We use the unintegrated Parton Density Functions of the gluon obtained from a fit to measurements of the structure functions F2 and F2c at HERA to describe the experimental data fo…
Two-Loop Formfactors in Theories with Mass Gap and Z-Boson Production
A. Kotikov, J. H. Kuhn, O. Veretin
The two-loop formfactor both for a U(1)xU(1) and a SU(2)xU(1) gauge theory with massive and massless gauge bosons respectively is evaluated at arbitrary momentum transfer q^2. The…
Structure Function at Fixed in the -Factorization Approach
A. V. Kotikov, A. V. Lipatov, N. P. Zotov
The results for structure function , obtained in the -factorization and collinear approaches, are compared with recent H1 experimental data at fixed values.
Analytic continuation of the Mellin moments of deep inelastic structure functions
A. V. Kotikov, V. N. Velizhanin
We derive the analytic continuation of the Mellin moments of deep inelastic structure functions at the next-to-next-to-leading order accuracy.
Small x behavior of parton distributions with flat initial conditions. A study of higher-twist effects
A. V. Kotikov, G. Parente
We study the Q^2 evolution of parton distributions at small x values, obtained in the case of flat initial conditions. The contributions of twist-two and (renormalon-type) higher-t…
