  A search for narrow resonances with a mass of at least 1 TeV in the dijet
mass spectrum is performed using pp collisions at sqrt(s)=7 TeV corresponding
to an integrated luminosity of 1 inverse femtobarn, collected by the CMS
experiment at the LHC. No resonances are observed. Upper limits at the 95%
confidence level are presented on the product of the resonance cross section,
branching fraction into dijets, and acceptance, separately for decays into
quark-quark, quark-gluon, and gluon-gluon pairs. The data exclude new particles
predicted in the following models at the 95% confidence level: string
resonances with mass less than 4.00 TeV, E6 diquarks with mass less than 3.52
TeV, excited quarks with mass less than 2.49 TeV, axigluons and colorons with
mass less than 2.47 TeV, and W' bosons with mass less than 1.51 TeV.
