Abstract (data abstract)
A search for resonances and quantum black holes is performed using the dijet mass spectra measured in proton-proton collisions at $\sqrt{s}$=8 TeV with the CMS detector at the LHC. The data set corresponds to an integrated luminosity of 19.7 fb$^{-1}$. In a search for narrow resonances that couple to quark-quark, quark-gluon, or gluon-gluon pairs, model-independent upper limits, at 95% confidence level, are obtained on the production cross section of resonances, with masses above 1.2 TeV. When interpreted in the context of specific models the limits exclude: string resonances with masses below 5.0 TeV; excited quarks below 3.5 TeV; scalar diquarks below 4.7 TeV; W.
