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…

Mass Terms in Two-Higgs Doublet Models
R. Santos, S. M. Oliveira, A. Barroso
We take a closer look at the mass terms of all renormalizable and CP conserving two-Higgs doublet models (THDM). We show how some of the dimension two parameters in the potential c…
