Phenomenology of electro-weak bosons at hadron colliders with novel variables
Abstract
We review the phenomenology of electro-weak bosons produced in hadron-hadron collisions. In particular, we discuss the transverse momentum distribution of lepton pairs with invariant mass close to the Z peak. We describe the theoretical calculation for the magnitude of the transverse momentum QT and its comparison to Tevatron and LHC data. We also discuss the related variable φ*, describing its experimental advantages as well as its relation to the standard QT variable. Finally, we compare resummed predictions for φ* to data.
