Weak vector boson production with many jets at the LHC s=13  TeV.

Anger, F. R. and Febres Cordero, F. and Höche, S. and Maître, D. (2018) 'Weak vector boson production with many jets at the LHC s=13  TeV.', Physical review D., 97 (9). 096010.


Signatures with an electroweak vector boson and many jets play a crucial role at the Large Hadron Collider, both in the measurement of Standard-Model parameters and in searches for new physics. Precise predictions for these multiscale processes are therefore indispensable. We present next-to-leading order QCD predictions for W=Z þ jets at ffiffi s p ¼ 13 TeV, including up to five/four jets in the final state. All production channels are included, and leptonic decays of the vector bosons are considered at the amplitude level. We assess theoretical uncertainties arising from renormalization- and factorization-scale dependence by considering fixed-order dynamical scales based on the HT variable as well as on the MiNLO procedure. We also explore uncertainties associated with different choices of parton-distribution functions. We provide event samples that can be explored through publicly available n-tuple sets, generated with BLACKHAT in combination with SHERPA.
