| Abstract: A measurement of the electroweak production of ZV (V = W, Z) boson pairs associated with two jets in proton-proton collisions at a center-of-mass energy of 13 TeV is presented. The analysis targets final states with two isolated electrons or muons from Z decays and three to four jets, depending on the momentum of the vector boson that decays into quarks. The data, corresponding to an integrated luminosity of 138 fb$ ^{-1} $, were collected at the CERN LHC with the CMS detector during the 2016--2018 data-taking period. The cross section is measured in a fiducial region characterized by a large invariant mass and pseudorapidity gap between the two forward jets. The electroweak production of ZV in association with two jets is measured with an observed (expected) significance of 1.3 (1.8) standard deviations. Constraints are also placed on effective field theory parameters that describe anomalous electroweak production of WW, WZ, and ZZ boson pair pairs in association with two jets, combining the ZV and WV semileptonic events. Stringent limits are set on anomalous quartic gauge couplings in terms of dimension-8 operators. | ||
