Descripción
A search is presented for physics beyond the standard model, based on
measurements of dijet angular distributions in proton-proton collisions
at √{s}=13TeV. The data collected with the CMS detector at the LHC
correspond to an integrated luminosity of 35.9 {fb}^{-1}. The observed
distributions, corrected to particle level, are found to be in agreement
with predictions from perturbative quantum chromodynamics that include
electroweak corrections. Constraints are placed on models containing
quark contact interactions, extra spatial dimensions, quantum black
holes, or dark matter, using the detector-level distributions. In a
benchmark model where only left-handed quarks participate, contact
interactions are excluded at the 95% confidence level up to a scale of
12.8 or 17.5TeV, for destructive or constructive interference,
respectively. The most stringent lower limits to date are set on the
ultraviolet cutoff in the Arkani-Hamed-Dimopoulos-Dvali model of extra
dimensions. In the Giudice-Rattazzi-Wells convention, the cutoff scale
is excluded up to 10.1TeV. The production of quantum black holes is
excluded for masses below 5.9 and 8.2TeV, depending on the model. For
the first time, lower limits between 2.0 and 4.6TeVare set on the mass
of a dark matter mediator for (axial-)vector mediators, for the
universal quark coupling g_{q} =1.0.
