FEATURES OF SINGLE LEPTON PRODUCTION AT HADRON COLLIDER

Abstract

In the Born approximation, as in the next-to-leading order approximation, Single lepton production $p\bar{p}\to l^{\pm }\nu X$ at Fermilab Tevatron is discussed. The effects of non standard model physics ($W^{\prime }$ - production) are also considered. It was shown that $2\to 3$ subprocesses play important role when a high transverse momentum cut on the lepton is imposed. On the other hand the NLO corrections do not cause qualitative changes of Born approximation results. The contributions of $W^{\prime }$ bosons for this signature become more important for large values of $P_T^{cut}$.
