Abstract
A search has been performed for heavy resonances decaying to ZZ or ZW in
2l2q final states, with two charged leptons (l = e, mu) produced by the
decay of a Z boson, and two quarks produced by the decay of a W or Z
boson. The analysis is sensitive to resonances with masses in the range
from 400 to 4500 GeV. Two categories are defined based on the merged or
resolved reconstruction of the hadronically decaying vector boson,
optimized for high- and low-mass resonances, respectively. The search is
based on data collected during 2016 by the CMS experiment at the LHC in
proton-proton collisions with a center-of-mass energy of root s = 13
TeV, corresponding to an integrated luminosity of 35.9 fb(-1). No excess
is observed in the data above the standard model background expectation.
Upper limits on the production cross section of heavy, narrow spin-1 and
spin-2 resonances are derived as a function of the resonance mass, and
exclusion limits on the production of W' bosons and bulk graviton
particles are calculated in the framework of the heavy vector triplet
model and warped extra dimensions, respectively.
