Remarkable virtual SUSY effects in $W^{\pm }$ production at high energy hadron colliders

Abstract

We present a complete 1-loop study of the electroweak corrections to the process $ug\to d{W}^{+}$ in MSSM and SM. The occurrence of a number of remarkable properties in the behavior of the helicity amplitudes at high energies is stressed, and the crucial role of the virtual SUSY contributions in establishing them, is emphasized. The approach to asymptopia of these amplitudes is discussed, comparing the effects of the logarithmic and constant contributions to the mass suppressed ones, which are relevant at lower energies. Applying crossing to $ug\to d{W}^{+}$, we obtain all subprocesses needed for the 1-loop electroweak corrections to $W^{\pm }$-production at LHC. The SUSY model dependence of such a production is then studied, and illustrations are given for the transverse $W^{\pm }$ momentum distribution, as well as the angular distribution in the subprocess center of mass.
