Study of the dijet mass spectrum in pp?W+jets events at vs=7 TeV

Abstract: We report an investigation of the invariant mass spectrum of the two jets with highest transverse momentum in pp ! W þ 2-jet and W þ 3-jet events to look for resonant enhancement. The data sample corresponds to an integrated luminosity of 5:0 fb1 collected with the CMS detector at ffiffiffis p ¼ 7 TeV. We find no evidence for the anomalous structure reported by the CDF Collaboration, and establish an upper limit of 5.0 pb at 95% confidence level on the production cross section for a generic Gaussian signal with mass near 150 GeV. Additionally, we exclude two theoretical models that predict a CDF-like dijet resonance near 150 GeV.
