Query: Search for quark contact interactions and extra spatial dimensions using
  dijet angular distributions in proton-proton collisions at sqrt(s) = 8 TeV   A search is presented for quark contact interactions and extra spatial
dimensions in proton-proton collisions at sqrt(s) = 8 TeV using dijet angular
distributions. The search is based on a data set corresponding to an integrated
luminosity of 19.7 inverse femtobarns collected by the CMS detector at the CERN
LHC. Dijet angular distributions are found to be in agreement with the
perturbative QCD predictions that include electroweak corrections. Limits on
the contact interaction scale from a variety of models at next-to-leading order
in QCD corrections are obtained. A benchmark model in which only left-handed
quarks participate is excluded up to a scale of 9.0 (11.7) TeV for destructive
(constructive) interference at 95% confidence level. Lower limits between 5.9
and 8.4 TeV on the scale of virtual graviton exchange are extracted for the
Arkani-Hamed--Dimopoulos--Dvali model of extra spatial dimensions.
