CMS Collaboration

A study is presented of the invariant mass spectrum of the two jets with highest transverse momentum in pp to W+2-jet and W+3-jet events. The data sample corresponds to an integrated luminosity of 5.0 inverse femtobarns collected with the CMS detector at sqrt(s)=7 TeV. No evidence is found for the anomalous structure reported by the CDF Collaboration, and an upper limit of 5.0 pb is established at 95% confidence level on the production cross section for a generic Gaussian signal with mass near 150 GeV. Two theoretical models that predict a dijet resonance near 150 GeV are excluded.
