Parametrization of the QCD coupling in Hard and Regge processes
B. I. Ermolaev, S. I. Troyan
We examine the parametrization of the QCD coupling in the Bethe-Salpeter equations for the hard and Regge processes and determine the argument of alpha_s of the factorized gluon. O…
Description of the spin structure function g_1 at arbitrary and arbitrary Q^2
B. I. Ermolaev, M. Greco, S. I. Troyan
The explicit expressions describing the structure function g_1 at arbitrary x and Q^2 are obtained. In the first place, they combine the well-known DGLAP expressions for g_1 with t…
Spin structure function g_1 at small x and arbitrary $Q^2: Total resummaion of leading logarithms vs Standard Approach
B. I. Ermolaev, M. Greco, S. I. Troyan
The Standard Approach (SA) for description of the structure function g_1 combines the DGLAP evolution equations and Standard Fits for the initial parton densities. The DGLAP equati…
Spin-Dependent Structure Function g_1 at Small x
B. I. Ermolaev, M. Greco, S. I. Troyan
Accounting for double-logarithms of x and running QCD coupling leads to expressions for both the non-singlet and singlet components of . These expressions manifest the Regge a…
Impact of the running QCD coupling on the value of the intercept of the structure function singlet
B. I. Ermolaev, M. Greco, S. I. Troyan
The running QCD coupling effects for singlet are studied. We predict that asymptotically , with the singlet intercept .
Forward-Backward Charge Asymmetry at Very High Energies
B. I. Ermolaev, M. Greco, S. M. Oliveira +1
The impact of the electroweak radiative corrections on the value of the forward-backward asymmetry in e^+ e^- annihilation into a quark-antiquark pair is considered in the double-l…
