Measurement of top quark-antiquark pair production in association with a W or Z boson in pp collisions at √s=8 TeV
(2014)The European Physical Journal CA measurement of the cross section for the production of top quark–antiquark pairs (tt¯) in association with a vector boson V (W or Z) in proton-proton collisions at s√=8 TeV is presented. The results are based on a dataset corresponding to an integrated luminosity of 19.5 fb−1 recorded with the CMS detector at the LHC. The measurement is performed in three leptonic (e and μ) channels: a same-sign dilepton analysis targeting tt¯W events, ...Journal Article -
Observation of the diphoton decay of the Higgs boson and measurement of its properties
(2014)The European Physical Journal CObservation of the diphoton decay mode of the recently discovered Higgs boson and measurement of some of its properties are reported. The analysis uses the entire dataset collected by the CMS experiment in proton-proton collisions during the 2011 and 2012 LHC running periods. The data samples correspond to integrated luminosities of 5.1fb-1at s√=7TeV and 19.7fb-1at 8TeV . A clear signal is observed in the diphoton channel at a mass close ...Journal Article -
Search for neutral MSSM Higgs bosons decaying to a pair of tau leptons in pp collisions
(2014)Journal of High Energy PhysicsA search for neutral Higgs bosons in the minimal supersymmetric extension of the standard model (MSSM) decaying to tau-lepton pairs in pp collisions is performed, using events recorded by the CMS experiment at the LHC. The dataset corresponds to an integrated luminosity of 24.6 fb−1, with 4.9 fb−1 at 7 TeV and 19.7 fb−1 at 8 TeV. To enhance the sensitivity to neutral MSSM Higgs bosons, the search includes the case where the Higgs boson ...Journal Article -
Search for the associated production of the Higgs boson with a top-quark pair
(2014)Journal of High Energy PhysicsA search for the standard model Higgs boson produced in association with a top-quark pair (tt¯H) is presented, using data samples corresponding to integrated luminosities of up to 5.1 fb−1 and 19.7 fb−1 collected in pp collisions at center-of-mass energies of 7 TeV and 8 TeV respectively. The search is based on the following signatures of the Higgs boson decay: H → hadrons, H → photons, and H → leptons. The results are characterized by ...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
