Measurement of the Wγ and Zγ inclusive cross sections in pp collisions at √s=7 TeV and limits on anomalous triple gauge boson couplings
(2014)Physical Review DMeasurements of Wγ and Zγ production in proton-proton collisions at √s=7 TeV are used to extract limits on anomalous triple gauge couplings. The results are based on data recorded by the CMS experiment at the LHC that correspond to an integrated luminosity of 5.0 fb−1. The cross sections are measured for photon transverse momenta pγT>15 GeV, and for separations between photons and final-state charged leptons in the pseudorapidity-azimuthal ...Journal Article -
Search for new physics in events with same-sign dileptons and jets in pp collisions at √8 = 8 TeV
(2014)Journal of High Energy PhysicsA search for new physics is performed based on events with jets and a pair of isolated, same-sign leptons. The results are obtained using a sample of proton-proton collision data collected by the CMS experiment at a centre-of-mass energy of 8 TeV at the LHC, corresponding to an integrated luminosity of 19.5 fb−1. In order to be sensitive to a wide variety of possible signals beyond the standard model, multiple search regions defined by ...Journal Article -
Identification techniques for highly boosted W bosons that decay into hadrons
(2014)Journal of High Energy PhysicsIn searches for new physics in the energy regime of the LHC, it is becoming increasingly important to distinguish single-jet objects that originate from the merging of the decay products of W bosons produced with high transverse momenta from jets initiated by single partons. Algorithms are defined to identify such W jets for different signals of interest, using techniques that are also applicable to other decays of bosons to hadrons that ...Journal Article
