Description
A search is presented for massive narrow resonances decaying either into
two Higgs bosons, or into a Higgs boson and a W or Z boson. The decay
channels considered are HH\to
b\overline{b}{τ}+{τ}- and VH\to
q\overline{q}{τ}+{τ}- , where H denotes
the Higgs boson, and V denotes the W or Z boson. This analysis is based
on a data sample of proton-proton collisions collected at a
center-of-mass energy of 13 TeV by the CMS Collaboration, corresponding
to an integrated luminosity of 35.9 fb-1. For the TeV-scale
mass resonances considered, substructure techniques provide ways to
differentiate among the hadronization products from vector boson decays
to quarks, Higgs boson decays to bottom quarks, and quark- or
gluon-induced jets. Reconstruction techniques are used that have been
specifically optimized to select events in which the tau lepton pair is
highly boosted. The observed data are consistent with standard model
expectations and upper limits are set at 95% confidence level on the
product of cross section and branching fraction for resonance masses
between 0.9 and 4.0 TeV. Exclusion limits are set in the context of bulk
radion and graviton models:spin-0 radion resonances are excluded below a
mass of 2.7 TeV at 95% confidence level. In the spin-1 heavy vector
triplet framework, mass-degenerate W' and Z' resonances with dominant
couplings to the standard model gauge bosons are excluded below a mass
of 2.8 TeV at 95% confidence level. These are the first limits for
massive resonances at the TeV scale with these decay channels at
√{s}=13 TeV.
