Search for new resonances decaying via WZ to leptons in proton-proton collisions at √s=8TeV
(2015)Physics Letters BA search is performed in proton–proton collisions at s=8 TeV for exotic particles decaying via WZ to fully leptonic final states with electrons, muons, and neutrinos. The data set corresponds to an integrated luminosity of 19.5 fb−1. No significant excess is observed above the expected standard model background. Upper bounds at 95% confidence level are set on the production cross section of a W′ boson as predicted by an extended gauge ...Journal Article -
Performance of Photon Reconstruction and Identification with the CMS Detector in Proton-Proton Collisions at √s = 8 TeV
(2015)Journal of InstrumentationA description is provided of the performance of the CMS detector for photon reconstruction and identification in proton-proton collisions at a centre-of-mass energy of 8 TeV at the CERN LHC. Details are given on the reconstruction of photons from energy deposits in the electromagnetic calorimeter (ECAL) and the extraction of photon energy estimates. The reconstruction of electron tracks from photons that convert to electrons in the CMS ...Journal Article -
Search for Long-Lived Neutral Particles Decaying to Quark-Antiquark Pairs in Proton-Proton Collisions at √s = 8 TeV
(2015)Physical Review DA search is performed for long-lived massive neutral particles decaying to quark-antiquark pairs. The experimental signature is a distinctive topology of a pair of jets, originating at a secondary vertex. Events were collected with the CMS detector at the CERN LHC in proton-proton collisions at a center-of-mass energy of 8 TeV. The data analyzed correspond to an integrated luminosity of 18.5 fb−1. No significant excess is observed above ...Journal Article -
Search for long-lived particles that decay into final states containing two electrons or two muons in proton-proton collisions at √s = 8 TeV
(2015)Physical Review DA search is performed for long-lived particles that decay into final states that include a pair of electrons or a pair of muons. The experimental signature is a distinctive topology consisting of a pair of charged leptons originating from a displaced secondary vertex. Events corresponding to an integrated luminosity of 19.6 (20.5) fb−1 in the electron (muon) channel were collected with the CMS detector at the CERN LHC in proton-proton ...Journal Article
