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…
Double-logarithmic (Sudakov) asymptotics at the theory of electroweak interactions
B. I. Ermolaev, M. Greco, S. M. Oliveira +1
Accounting for double-logarithmic contributions to high-energy (>> 100 GeV) e^+ e^- annihilation into a quark or a lepton pair in the kinematics where the final particles are colin…
On the Sudakov suppression and enhancement for electroweak reactions
B. I. Ermolaev
Accounting for the double-logarithmic (DL) contributions to amplitude of Z to f \bar{f} leads to the Sudakov suppression. In contrast, resumming DL contributions to amplitudes of W…
Accounting for running alpha_s for the non-singlet components of the structure functions F_1 and g_1 at small x
B. I. Ermolaev, M. Greco, S. I. Troyan
