Measurements of differential Z boson production cross sections in proton-proton collisions at √s = 13 TeV
(2019)Journal of High Energy PhysicsMeasurements are presented of the differential cross sections for Z bosons produced in proton-proton collisions at s√ = 13 TeV and decaying to muons and electrons. The data analyzed were collected in 2016 with the CMS detector at the LHC and correspond to an integrated luminosity of 35.9 fb−1. The measured fiducial inclusive product of cross section and branching fraction agrees with next-to-next-to-leading order quantum chromodynamics ...Journal Article -
Search for MSSM Higgs bosons decaying to μ+μ− in proton-proton collisions at s=13TeV
(2019)Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy PhysicsA search is performed for neutral non-standard-model Higgs bosons decaying to two muons in the context of the minimal supersymmetric standard model (MSSM). Proton-proton collision data recorded by the CMS experiment at the CERN Large Hadron Collider at a center-of-mass energy of 13 TeV were used, corresponding to an integrated luminosity of 35.9 fb-1. The search is sensitive to neutral Higgs bosons produced via the gluon fusion process ...Journal Article -
Combination of CMS searches for heavy resonances decaying to pairs of bosons or leptons
(2019)Physics Letters BA statistical combination of searches for heavy resonances decaying to pairs of bosons or leptons is presented. The data correspond to an integrated luminosity of 35.9 fb−1 collected during 2016 by the CMS experiment at the LHC in proton-proton collisions at a center-of-mass energy of 13 TeV. The data are found to be consistent with expectations from the standard model background. Exclusion limits are set in the context of models of spin-1 ...Journal Article -
Search for anomalous electroweak production of vector boson pairs in association with two jets in proton-proton collisions at 13 TeV
(2019)Physics Letters BA search for anomalous electroweak production of WW, WZ, and ZZ boson pairs in association with two jets in proton-proton collisions at s=13TeV at the LHC is reported. The data sample corresponds to an integrated luminosity of 35.9fb−1 collected with the CMS detector. Events are selected by requiring two jets with large rapidity separation and invariant mass, one or two leptons (electrons or muons), and a W or Z boson decaying hadronically. ...Journal Article -
Search for new physics in top quark production in dilepton final states in proton-proton collisions at √s=13TeV
(2019)The European Physical Journal CA search for new physics in top quark production is performed in proton-proton collisions at 13TeV. The data set corresponds to an integrated luminosity of 35.9fb−1 collected in 2016 with the CMS detector. Events with two opposite-sign isolated leptons (electrons or muons), and b quark jets in the final state are selected. The search is sensitive to new physics in top quark pair production and in single top quark production in association ...Journal Article -
Measurement of the average very forward energy as a function of the track multiplicity at central pseudorapidities in proton-proton collisions at √s=13TeV
(2019)The European Physical Journal CThe average total energy as well as its hadronic and electromagnetic components are measured with the CMS detector at pseudorapidities −6.6<η<−5.2 in proton-proton collisions at a centre-of-mass energy s√=13TeV. The results are presented as a function of the charged particle multiplicity in the region |η|<2. This measurement is sensitive to correlations induced by the underlying event structure over a very wide pseudorapidity region. The ...Journal Article -
Measurements of triple-differential cross sections for inclusive isolated-photon+jet events in p p collisions at √s=8TeV
(2019)The European Physical Journal CMeasurements are presented of the triple-differential cross section for inclusive isolated-photon+jet events in pp collisions at s√=8 TeV as a function of photon transverse momentum (pγT), photon pseudorapidity (ηγ), and jet pseudorapidity (ηjet).

Search for supersymmetry using Higgs boson to diphoton decays at √s = 13 TeV
(2019)Journal of High Energy PhysicsA search for supersymmetry (SUSY) is presented where at least one Higgs boson is produced and decays to two photons in the decay chains of pair-produced SUSY particles. Two analysis strategies are pursued: one focused on strong SUSY production and the other focused on electroweak SUSY production. The presence of charged leptons, additional Higgs boson candidates, and various kinematic variables are used to categorize events into search ...Journal Article -
Search for long-lived particles using nonprompt jets and missing transverse momentum with proton-proton collisions at s=13TeV

The data sample corresponds to an integrated luminosity of 137 of proton-proton collisions at a center-of-mass energy of 13 TeV collected by the CMS experiment at the CERN LHC in 2016–2018. Candidate signal events containing nonprompt jets are identified using the timing capabilities of the CMS electromagnetic calorimeter. ...Journal Article -
