Query: Search for excited quarks in the photon+jet final state in proton-proton
  collisions at sqrt(s) = 8 TeV   A search for excited quarks decaying into the photon+jet final state is
presented. The analysis is based on data corresponding to an integrated
luminosity of 19.7 inverse femtobarns collected by the CMS experiment in
proton-proton collisions at sqrt(s) = 8 TeV at the LHC. Events with photons and
jets with high transverse momenta are selected and the photon+jet invariant
mass distribution is studied to search for a resonance peak. The 95% confidence
level upper limits on the product of cross section and branching fraction are
evaluated as a function of the excited quark mass. Limits on excited quarks are
presented as a function of their mass and coupling strength; masses below 3.5
TeV are excluded at 95% confidence level for unit couplings to their standard
model partners.
