Search for anomalous electroweak production of WW/WZ/ZZ boson pairs in association with two jets in proton-proton collisions at 13 TeV

A search for anomalous electroweak production of WW, WZ, and ZZ boson pairs in association with two jets in proton-proton collisions at $13$ TeV is reported. The data sample corresponds to an integrated luminosity of $35.9$ fb$^{-1}$ collected with the CMS detector. Events are selected by requiring two jets with large rapidity separation and dijet mass, one or two leptons (electrons or muons), and a W or Z boson decaying hadronically. The hadronically decaying boson is reconstructed as one large-radius jet. Constraints on the structure of quartic vector boson interactions in the framework of dimension-8 effective field theory operators are reported. Stringent limits on parameters for the effective field theory operators S0, S1, M0, M1, M6, M7, T0, T1, and T2 are obtained. Constraints on charged Higgs boson production are also reported.
