Measurement of the differential cross sections for the associated production of a W boson and jets in proton-proton collisions at s√=13 TeV
(2017)Physical Review DA measurement of the differential cross sections for a W boson produced in association with jets in the muon decay channel is presented. The measurement is based on 13 TeV proton-proton collision data corresponding to an integrated luminosity of 2.2 fb−1, recorded by the CMS detector at the LHC. The cross sections are reported as functions of jet multiplicity, jet transverse momentum pT, jet rapidity, the scalar pT sum of the jets, and ...Journal Article -
Search for a light pseudoscalar Higgs boson produced in association with bottom quarks in pp collisions at √s=8 TeV
(2017)Journal of High Energy PhysicsA search for a light pseudoscalar Higgs boson (A) produced in association with bottom quarks and decaying into a muon pair is reported. The search uses 19.7 fb−1 of proton-proton collisions at a center-of-mass energy of 8 TeV, collected by the CMS experiment. No signal is observed in the dimuon mass range from 25 to 60 GeV. Upper limits on the cross section times branching fraction, σ(pp→bb¯¯¯A)B(A→μμ), are set.Journal Article -
Search for direct production of supersymmetric partners of the top quark in the all-jets final state in proton-proton collisions at √s=13 TeV
(2017)Journal of High Energy PhysicsA search for direct production of top squark pairs in events with jets and large transverse momentum imbalance is presented. The data are based on proton-proton collisions at a center-of-mass energy of 13 TeV, collected with the CMS detector in 2016 at the CERN LHC, and correspond to an integrated luminosity of 35.9 fb−1. The search considers a variety of R-parity conserving supersymmetric models, including ones for which the top squark ...Journal Article -
Search for top squark pair production in pp collisions at √s=13 TeV using single lepton events
(2017)Journal of High Energy PhysicsA search for top squark pair production in pp collisions at √s=13 TeV is performed using events with a single isolated electron or muon, jets, and a large transverse momentum imbalance. The results are based on data collected in 2016 with the CMS detector at the LHC, corresponding to an integrated luminosity of 35.9 fb−1. No significant excess of events is observed above the expectation from standard model processes. Exclusion limits are ...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 -
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 -

Two final states are analyzed, one containing a single electron, or muon, and missing transverse momentum, and the other containing multiple jets and no electrons or muons. No ...Journal Article -
Search for pair production of vector-like T and B quarks in single-lepton final states using boosted jet substructure in proton-proton collisions at s√=13 TeV

The data set was collected in 2015 by the CMS experiment at the LHC and corresponds to an integrated luminosity of up to 2.6 fb−1. The T and B quarks are assumed to decay through three possible channels into a heavy boson (either a W, Z or Higgs boson) and a third generation quark. This search is performed in final ...Journal Article -
Measurements of properties of the Higgs boson decaying into the four-lepton final state in pp collisions at s√=13 TeV
(2017)Journal of High Energy PhysicsProperties of the Higgs boson are measured in the H → ZZ → 4ℓ (ℓ = e, μ) decay channel. A data sample of proton-proton collisions at s√=13 TeV, collected with the CMS detector at the LHC and corresponding to an integrated luminosity of 35.9 fb−1 is used.
