Abstract
At hadron colliders the production of a Z boson in association with jets represents an irreducible Standard Model background to direct searches for New Physics based on the signatures with several jets and missing transverse momentum. Using the algorithm developed by Denner and Pozzorini recently implemented in the ALPGEN event generator, one loop virtual weak corrections to Z+2 and Z+3 jets in the Sudakov limit have been computed. For the standard event selection considered by the ATLAS and CMS Collaborations, these corrections can grow up to −40, −45% at √s = 14Tev and become even larger at future proton-proton colliders where the higher energies will allow to study more and more extreme kinematical regions. Finally, also the effect of real weak corrections to the processes to Z + 2 and Z + 3 jets is briefly discussed.
