Search for an exotic decay of the Higgs boson to a pair of light pseudoscalars in the final state with two b quarks and two τ leptons in proton–proton collisions at s=13TeV
(2018)Physics Letters BA search for an exotic decay of the Higgs boson to a pair of light pseudoscalar bosons is performed for the first time in the final state with two b quarks and two τ leptons. The search is motivated in the context of models of physics beyond the standard model (SM), such as two Higgs doublet models extended with a complex scalar singlet (2HDM + S), which include the next-to-minimal supersymmetric SM (NMSSM). The results are based on a ...Journal Article -
Search for light pseudoscalar boson pairs produced from decays of the 125 GeV Higgs boson in final states with two muons and two nearby tracks in pp collisions at s=13TeV
(2020)Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy PhysicsA search is presented for pairs of light pseudoscalar bosons, in the mass range from 4 to 15 GeV, produced from decays of the 125 GeV Higgs boson. The decay modes considered are final states that arise when one of the pseudoscalars decays to a pair of tau leptons, and the other one either into a pair of tau leptons or muons. The search is based on proton-proton collisions collected by the CMS experiment in 2016 at a center-of-mass energy ...Journal Article -
Observation of prompt J/ψ meson elliptic flow in high-multiplicity pPb collisions at √s=8.16 TeV
(2019)Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy PhysicsA measurement of the elliptic flow (v2) of prompt J/Ψ mesons in high-multiplicity pPb collisions is reported using data collected by the CMS experiment at a nucleon-nucleon center-of-mass energy √sNN=8.16 TeV. Prompt J/Ψ mesons decaying into two muons are reconstructed in the rapidity region in the nucleon-nucleon center-of-mass frame (Ycm), corresponding to either -2.86 < Ycm < -1.86 or 0.94 < Ycm y 1.94. The average v2 result from the ...Journal Article -
Measurements of the associated production of a Z boson and b jets in pp collisions at √s = 8 TeV
(2017)The European Physical Journal CMeasurements of the associated production of a Z boson with at least one jet originating from a b quark in proton–proton collisions at √s=8TeV are presented. Differential cross sections are measured with data collected by the CMS experiment corresponding to an integrated luminosity of 19.8fb−1. Z bosons are reconstructed through their decays to electrons and muons. Cross sections are measured as a function of observables characterizing ...Journal Article -
Search for Supersymmetry with a Compressed Mass Spectrum in Events with a Soft τ Lepton, a Highly Energetic Jet, and Large Missing Transverse Momentum in Proton-Proton Collisions at √s = 13 TeV
(2020)Physical Review LettersThe first search for supersymmetry in events with an experimental signature of one soft, hadronically decaying τ lepton, one energetic jet from initial-state radiation, and large transverse momentum imbalance is presented. These event signatures are consistent with direct or indirect production of scalar τ leptons (˜τ) in supersymmetric models that exhibit coannihilation between the ˜τ and the lightest neutralino (˜χ01), and that could ...Journal Article -
Search for vectorlike leptons in multilepton final states in proton-proton collisions at s =13 TeV
(2019)Physical Review DA search for vectorlike leptons in multilepton final states is presented. The data sample corresponds to an integrated luminosity of 77.4 fb−1 of proton-proton collisions at a center-of-mass energy of 13 TeV collected by the CMS experiment at the LHC in 2016 and 2017. Events are categorized by the multiplicity of electrons, muons, and hadronically decaying τ leptons. The missing transverse momentum and the scalar sum of the lepton ...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 -
Search for a narrow, spin-2 resonance decaying to a pair of Z bosons in the qq¯ℓ+ℓ− final state
(2013)Physics Letters BResults are presented from a search for a narrow, spin-2 resonance decaying into a pair of Z bosons, with one Z-boson decaying into leptons (e+e− or μ+μ−) and the other into jets. An example of such a resonance is the Kaluza–Klein graviton, GKK, predicted in Randall–Sundrum models. The analysis is based on a 4.9 fb−1 sample of proton–proton collisions at a center-of-mass energy of 7 TeV, collected with the CMS detector at the LHC. Kinematic ...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
