Search for Dark Matter and Supersymmetry with a Compressed Mass Spectrum in the Vector Boson Fusion Topology in Proton-Proton Collisions at √s=8 TeV
(2017)Physical Review LettersA first search for pair production of dark matter candidates through vector boson fusion in proton-proton collisions at √s=8 TeV is performed with the CMS detector. The vector boson fusion topology enhances missing transverse momentum, providing a way to probe supersymmetry, even in the case of a compressed mass spectrum. The data sample corresponds to an integrated luminosity of 18.5 fb−1, recorded by the CMS experiment. The observed ...Journal Article -
Search for high-mass Zγ resonances in e+e−γ and μ+μ−γ final states in proton-proton collisions at √s=8 and 13 TeV
(2017)Journal of High Energy PhysicsThis paper describes the search for a high-mass narrow-width scalar particle decaying into a Z boson and a photon. The analysis is performed using proton-proton collision data recorded with the CMS detector at the LHC at center-of-mass energies of 8 and 13 TeV, corresponding to integrated luminosities of 19.7 and 2.7 fb−1, respectively. The Z bosons are reconstructed from opposite-sign electron or muon pairs. No statistically significant ...Journal Article -
Search for R-parity violating supersymmetry with displaced vertices in proton-proton collisions at √s = 8 TeV
(2017)Physical Review DResults are reported from a search for R-parity violating supersymmetry in proton-proton collision events collected by the CMS experiment at a center-of-mass energy of √s=8 TeV. The data sample corresponds to an integrated luminosity of 17.6 fb−1. This search assumes a minimal flavor violating model in which the lightest supersymmetric particle is a long-lived neutralino or gluino, leading to a signal with jets emanating from displaced ...Journal Article -
Search for supersymmetry in events with one lepton and multiple jets in proton-proton collisions at √s = 13 TeV
(2017)Physical Review DA search for supersymmetry is performed in events with a single electron or muon in proton-proton collisions at a center-of-mass energy of 13 TeV. The data were recorded by the CMS experiment at the LHC and correspond to an integrated luminosity of 2.3 fb−1. Several exclusive search regions are defined based on the number of jets and b-tagged jets, the scalar sum of the jet transverse momenta, and the scalar sum of the missing transverse ...Journal Article
