Description

qT subtraction represents a well established and successful formalism to deal with the computation of QCD radiative corrections up to NNLO (and beyond) for a large class of processes relevant at the LHC. We have explored the possibility to extend qT subtraction to the computation of EW corrections with the (final) aim to develop a subtraction formalism suitable for the computation of mixed QCDXEW corrections. We present numerical results for the complete NLO EW corrections to the Drell-Yan production of a massive lepton pair.
Furthermore, we have investigated the structure of the power suppressed contributions at small-qT in this process and present new analytical results on the effects of the soft radiation emitted off a charged massive final state.
