Search for anomalous Wtb couplings and flavour-changing neutral currents in t-channel single top quark production in pp collisions at √s=7 and 8 TeV
(2017)Journal of High Energy PhysicsSingle top quark events produced in the t channel are used to set limits on anomalous Wtb couplings and to search for top quark flavour-changing neutral current (FCNC) interactions. The data taken with the CMS detector at the LHC in proton-proton collisions at s√=7 and 8 TeV correspond to integrated luminosities of 5.0 and 19.7 fb−1, respectively. The analysis is performed using events with one muon and two or three jets. A Bayesian neural ...Journal Article -
Search for heavy resonances decaying to tau lepton pairs in proton-proton collisions at √s=13 TeV
(2017)Journal of High Energy PhysicsA search for heavy resonances that decay to tau lepton pairs is performed using proton-proton collisions at s√=13 TeV. The data were collected with the CMS detector at the CERN LHC and correspond to an integrated luminosity of 2.2 fb−1. The observations are in agreement with standard model predictions. An upper limit at 95% confidence level on the product of the production cross section and branching fraction into tau lepton pairs is ...Journal Article -
Searches for invisible decays of the Higgs boson in pp collisions at √s = 7, 8, and 13 TeV
(2017)Journal of High Energy PhysicsSearches for invisible decays of the Higgs boson are presented. The data collected with the CMS detector at the LHC correspond to integrated luminosities of 5.1, 19.7, and 2.3 fb−1 at centre-of-mass energies of 7, 8, and 13 TeV, respectively. The search channels target Higgs boson production via gluon fusion, vector boson fusion, and in association with a vector boson. Upper limits are placed on the branching fraction of the Higgs boson ...Journal Article -
Measurement of the total and differential inclusive B+ hadron cross sections in pp collisions at √s = 13 TeV
(2017)Physics Letters BThe differential cross sections for inclusive production of B+ hadrons are measured as a function of the B+ transverse momentum pTB and rapidity yB in pp collisions at a centre-of-mass energy of 13 TeV, using data collected by the CMS experiment that correspond to an integrated luminosity of 48.1 pb−1. The measurement uses the exclusive decay channel B+→J/ψK+, with J/ψ mesons that decay to a pair of muons. The results show a reasonable ...Journal Article -
Search for top squark pair production in compressed-mass-spectrum scenarios in proton-proton collisions at √s = 8 TeV using the αT variable
(2017)Physics Letters BAn inclusive search is performed for supersymmetry in final states containing jets and an apparent imbalance in transverse momentum, p→Tmiss, due to the production of unobserved weakly interacting particles in pp collisions at a centre-of-mass energy of 8 TeV. The data, recorded with the CMS detector at the CERN LHC, correspond to an integrated luminosity of 18.5 fb−1. The dimensionless kinematic variable αTαT is used to discriminate ...Journal Article -
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 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 -
Inclusive search for supersymmetry using razor variables in pp collisions at √s = 13 TeV
(2017)Physical Review DAn inclusive search for supersymmetry using razor variables is performed in events with four or more jets and no more than one lepton. The results are based on a sample of proton-proton collisions corresponding to an integrated luminosity of 2.3 fb−1 collected with the CMS experiment at a center-of-mass energy of √s = 13 TeV. No significant excess over the background prediction is observed in data, and 95% confidence level exclusion limits ...Journal Article
