Phenomenological studies of top-pair production at Next-to-Leading order

Abstract

The calculation of NLO QCD corrections to the $t\bar{t}\to W^{+}{W}^{-}b\bar{b}\to e^{+}{\nu }_e{\mu }^{-}{\bar{\nu }}_{\mu }b\bar{b}$ process with complete off-shell effects, is briefly summarized. Besides the total cross section and its scale dependence, a few differential distributions at the TeVatron run II and LHC are given. All results presented in this contribution have been obtained with the help of the HELAC-NLO Monte Carlo framework.
