Search for VBF produced diboson resonances in the all-jets final state at √s=13 TeV with the CMS experiment — •Irene Zoi, Robin Aggleton, and Andreas Hinzmann — Universität Hamburg

Many models of physics beyond the Standard Model (SM) predict the existence of heavy particles that decay to SM vector boson pairs. This talk presents a search for massive resonances produced through vector-boson-fusion (VBF) and decaying into a pair of vector bosons (WW, WZ or ZZ) where each boson decays to a quark anti-quark pair, extending the previously published searches optimized for production via gluon-fusion and quark anti-quark annihilation. The analysis is based on proton-proton collision data at √s = 13 TeV collected by the CMS experiment at the CERN LHC during 2016 and corresponding to an integrated luminosity of 35.9 fb⁻¹. The signals studied in this analysis are narrow resonances with masses above 1.0 TeV, that decay to energetic vector bosons, considering various spin hypotheses. The particles emerging from each vector boson are very collimated and therefore merged into a single boosted jet. Jet substructure techniques are exploited to significantly reduce the SM background.
