Abstract
A search is presented for narrow resonances decaying to dijet final states in proton–proton collisions at
√s = 13 TeV using data corresponding to an integrated luminosity of 12.9 fb−1. The dijet mass spectrum
is well described by a smooth parameterization and no significant 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 7.4 TeV, scalar diquarks below 6.9 TeV, axigluons and
colorons below 5.5 TeV, excited quarks below 5.4 TeV, color-octet scalars below 3.0 TeV, W bosons below
2.7 TeV, Z bosons below 2.1 TeV and between 2.3 and 2.6 TeV, and RS gravitons below 1.9 TeV. These
extend previous limits in the dijet channel. Vector and axial-vector mediators in a simplified model of
interactions between quarks and dark matter are excluded below 2.0 TeV. The first limits in the dijet
channel on dark matter mediators are presented as functions of dark matter mass and are compared to
the exclusions of dark matter in direct detection experiments.
