, where , � = e,μ. The analysis is based on a
data sample of proton-proton collisions at √s = 13 TeV at the LHC collected with the CMS detector and
corresponding to an integrated luminosity of 35.9 fb−1. The WZ plus two jet production cross section is
measured in fiducial regions with enhanced contributions from EW production and found to be consistent
with standard model predictions. The EW WZ production in association with two jets is measured with
an observed (expected) significance of 2.2 (2.5) standard deviations. Constraints on charged Higgs boson
production and on anomalous quartic gauge couplings in terms of dimension-eight effective field theory
operators are also presented |
