Measurement of the Isolated Prompt Photon Production Cross Section in pp Collisions at √s=7 TeV
(2011)Physical Review LettersThe differential cross section for the inclusive production of isolated prompt photons has been measured as a function of the photon transverse energy EγT in pp collisions at √s=7 TeV using data recorded by the CMS detector at the LHC. The data sample corresponds to an integrated luminosity of 2.9 pb−1. Photons are required to have a pseudorapidity |ηγ|<1.45 and EγT>21 GeV, covering the kinematic region 0.006<xT<0.086. The measured ...Journal Article -
Search for Signatures of Extra Dimensions in the Diphoton Mass Spectrum at the Large Hadron Collider
(2012)Physical Review LettersA search for signatures of extra spatial dimensions in the diphoton invariant-mass spectrum has been performed with the CMS detector at the LHC. No excess of events above the standard model expectation is observed using a data sample collected in proton-proton collisions at √s=7 TeV corresponding to an integrated luminosity of 2.2 fb−1. In the context of the large-extra-dimensions model, lower limits are set on the effective Planck scale ...Journal Article -
Search for Quark Compositeness with the Dijet Centrality Ratio in pp Collisions at √s=7 TeV
(2010)Physical Review LettersA search for quark compositeness in the form of quark contact interactions, based on hadronic jet pairs (dijets) produced in proton-proton collisions at √s=7 TeV, is described. The data sample of the study corresponds to an integrated luminosity of 2.9 pb−1 collected with the CMS detector at the LHC. The dijet centrality ratio, which quantifies the angular distribution of the dijets, is measured as a function of the invariant mass of ...Journal Article -
Measurement of the t-Channel Single Top Quark Production Cross Section in pp Collisions at √s=7 TeV
(2011)Physical Review LettersElectroweak production of the top quark is measured for the first time in pp collisions at √s=7 TeV, using a data set collected with the CMS detector at the LHC and corresponding to an integrated luminosity of 36 pb−1. With an event selection optimized for t-channel production, two complementary analyses are performed. The first one exploits the special angular properties of the signal, together with background estimates from the data. ...Journal Article
