Description
Searches for resonances decaying into pairs of jets are performed using
proton-proton collision data collected at √{s}=13 TeV corresponding
to an integrated luminosity of up to 36 fb-1. A low-mass
search, for resonances with masses between 0.6 and 1.6 TeV, is performed
based on events with dijets reconstructed at the trigger level from
calorimeter information. A high-mass search, for resonances with masses
above 1.6 TeV, is performed using dijets reconstructed offline with a
particle-flow algorithm. The dijet mass spectrum is well described by a
smooth parameterization and no evidence for the production of new
particles is observed. Upper limits at 95% confidence level are reported
on the production cross section for narrow resonances with masses above
0.6 TeV. In the context of specific models, the limits exclude string
resonances with masses below 7.7 TeV, scalar diquarks below 7.2 TeV,
axigluons and colorons below 6.1 TeV, excited quarks below 6.0 TeV,
color-octet scalars below 3.4 TeV, W' bosons below 3.3 TeV,
Z' bosons below 2.7 TeV, Randall-Sundrum gravitons below 1.8
TeV and in the range 1.9 to 2.5 TeV, and dark matter mediators below 2.6
TeV. The limits on both vector and axial-vector mediators, in a
simplified model of interactions between quarks and dark matter
particles, are presented as functions of dark matter particle mass and
coupling to quarks. Searches are also presented for broad resonances,
including for the first time spin-1 resonances with intrinsic widths as
large as 30% of the resonance mass. The broad resonance search improves
and extends the exclusions of a dark matter mediator to larger values of
its mass and coupling to quarks.
