Gluon density in the rescaling model
N. A. Abdulov, A. V. Kotikov, A. V. Lipatov
The behavior of the gluon density in nuclei is investigated in the framework of the rescaling model.
Sunrise integral in non-relativistic QCD with elliptics
A. V. Kotikov
The main steps of the process of obtaining the result [1] in terms of elliptic polylogarithms for a two-loop sunrise integral with two different internal masses with pseudothreshol…
Parametrizations of collinear and k_T-dependent parton densities in a proton
N. A. Abdulov, A. V. Kotikov, A. V. Lipatov
A new type of parametrization for parton distribution functions in a proton, based on their -evolution at large and small values, is constructed. In our analysis, the vale…
About Fractional Analytic QCD beyond Leading Order
A. V. Kotikov, I. A. Zemlyakov
We present an overview of fractional analytic QCD beyond leading order, following the results recently obtained in Ref. [1]. We demonstrate four different representations, the deta…
On series and integral representations of some NRQCD master integrals
M. A. Bezuglov, A. V. Kotikov, A. I. Onishchenko
We consider new ways of obtaining series and integral representations for master integrals arising in the process of matching of QCD to NRQCD. The latter results are exact in space…
alpha_s in DIS scheme
A. V. Kotikov, V. G. Krivokhizhin, B. G. Shaikhatdenov
Deep inelastic scattering data on structure function from various fixed-target experiments were analyzed in a nonsinglet approximation in the MSbar and DIS scheme. The study…
