Descripción
A search for narrow vector resonances decaying into quark-antiquark
pairs is presented. The analysis is based on data collected in
proton-proton collisions at √{s}=13 TeV with the CMS detector at
the LHC, corresponding to an integrated luminosity of 35.9
fb-1. The hypothetical resonance is produced with
sufficiently high transverse momentum that its decay products are merged
into a single jet with two-prong substructure. A signal would be
identified as a peak over a smoothly falling background in the
distribution of the invariant mass of the jet, using novel jet
substructure techniques. No evidence for such a resonance is observed
within the mass range of 50-300 GeV. Upper limits at 95% confidence
level are set on the production cross section, and presented in a
mass-coupling parameter space. The limits further constrain simplified
models of dark matter production involving a mediator interacting
between quarks and dark matter particles through a vector or
axial-vector current. In the framework of these models, the results are
the most sensitive to date, extending for the first time the search
region to masses below 100 GeV. [Figure not available: see fulltext.]
