Measurements of the pp → Wγγ and pp → Zγγ cross sections and limits on anomalous quartic gauge couplings at √s=8 TeV
(2017)Journal of High Energy PhysicsMeasurements are presented of Wγγ and Zγγ production in proton-proton collisions. Fiducial cross sections are reported based on a data sample corresponding to an integrated luminosity of 19.4 fb−1 collected with the CMS detector at a center-of-mass energy of 8 TeV. Signal is identified through the W → ℓν and Z → ℓℓ decay modes, where ℓ is a muon or an electron. The production of Wγγ and Zγγ, measured with significances of 2.6 and 5.9 ...Journal Article -
Search for new physics in the monophoton final state in proton-proton collisions at √s=13 TeV
(2017)Journal of High Energy PhysicsA search is conducted for new physics in a final state containing a photon and missing transverse momentum in proton-proton collisions at s√=13 TeV. The data collected by the CMS experiment at the CERN LHC correspond to an integrated luminosity of 12.9 fb−1. No deviations are observed relative to the predictions of the standard model. The results are interpreted as exclusion limits on the dark matter production cross sections and parameters ...Journal Article -
Search for heavy neutrinos or third-generation leptoquarks in final states with two hadronically decaying tau leptons and two jets in proton-proton collisions at √s = 13 TeV
(2017)Journal of High Energy PhysicsA search for new particles has been conducted using events with two high transverse momentum (pT) τ leptons that decay hadronically, at least two high-pT jets, and missing transverse energy from the τ lepton decays. The analysis is performed using data from proton-proton collisions, collected by the CMS experiment in 2015 at s √ =13 s=13 TeV, corresponding to an integrated luminosity of 2.1 fb−1. The results are interpreted in two ...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 -
Search for electroweak production of charginos and neutralinos in WH events in proton-proton collisions at √s=13 TeV
(2017)Journal of High Energy PhysicsResults are reported from a search for physics beyond the standard model in proton-proton collision events with a charged lepton (electron or muon), two jets identified as originating from a bottom quark decay, and significant imbalance in the transverse momentum. The search was performed using a data sample corresponding to 35.9 fb−1, collected by the CMS experiment in 2016 at s√=13 TeV. Events with this signature can arise, for example, ...Journal Article -
Measurements of differential cross sections for associated production of a W boson and jets in proton-proton collisions at √s = 8 TeV
(2017)Physical Review DDifferential cross sections for a W boson produced in association with jets are measured in a data sample of proton-proton collisions at a center-of-mass energy of 8 TeV recorded with the CMS detector and corresponding to an integrated luminosity of 19.6 fb−1. The W bosons are identified through their decay mode W→μν. The cross sections are reported as functions of jet multiplicity, transverse momenta, and the scalar sum of jet transverse ...Journal Article -
Measurement of electroweak-induced production of Wγ with two jets in pp collisions at s√=8 TeV and constraints on anomalous quartic gauge couplings
(2017)Journal of High Energy PhysicsA measurement of electroweak-induced production of Wγ and two jets is performed, where the W boson decays leptonically. The data used in the analysis correspond to an integrated luminosity of 19.7 fb−1 collected by the CMS experiment in s√=8 TeV proton-proton collisions produced at the LHC. Candidate events are selected with exactly one muon or electron, missing transverse momentum, one photon, and two jets with large rapidity separation. ...Journal Article -
Search for associated production of a Z boson with a single top quark and for tZ flavour-changing interactions in pp collisions at s√=8 TeV
(2017)Journal of High Energy PhysicsA search for the production of a single top quark in association with a Z boson is presented, both to identify the expected standard model process and to search for flavour-changing neutral current interactions. The data sample corresponds to an integrated luminosity of 19.7 fb−1 recorded by the CMS experiment at the LHC in proton-proton collisions at s√=8 TeV. Final states with three leptons (electrons or muons) and at least one jet are ...Journal Article -
Search for supersymmetry in events with at least one photon, missing transverse momentum, and large transverse event activity in proton-proton collisions at √s=13 TeV
(2017)Journal of High Energy PhysicsA search for physics beyond the standard model in final states with at least one photon, large transverse momentum imbalance, and large total transverse event activity is presented. Such topologies can be produced in gauge-mediated supersymmetry models in which pair-produced gluinos or squarks decay to photons and gravitinos via short-lived neutralinos. The data sample corresponds to an integrated luminosity of 35.9 fb−1 of proton-proton ...Journal Article
