Measurements of jet charge with dijet events in pp collisions at √s=8 TeV
(2017)Journal of High Energy PhysicsJet charge is an estimator of the electric charge of a quark, antiquark, or gluon initiating a jet. It is based on the momentum-weighted sum of the electric charges of the jet constituents. Measurements of three charge observables of the leading jet in transverse momentum p T are performed with dijet events. The analysis is carried out with ata collected by the CMS experiment at the CERN LHC in proton-proton collisions at √s=8 TeV ...Journal Article -
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 associated production of dark matter with a Higgs boson decaying to bb ¯ or γγ at √s=13 TeV
(2017)Journal of High Energy PhysicsA search for dark matter is performed looking for events with large missing transverse momentum and a Higgs boson decaying either to a pair of bottom quarks or to a pair of photons. The data from proton-proton collisions at a center-of-mass energy of 13 TeV, collected in 2015 with the CMS detector at the LHC, correspond to an integrated luminosity of 2.3 fb−1. Results are interpreted in the context of a Z′-two-Higgs-doublet model, where ...Journal Article -
Search for light bosons in decays of the 125 GeV Higgs boson in proton-proton collisions at √s=8 TeV
(2017)Journal of High Energy PhysicsA search is presented for decays beyond the standard model of the 125 GeV Higgs bosons to a pair of light bosons, based on models with extended scalar sectors. Light boson masses between 5 and 62.5 GeV are probed in final states containing four τ leptons, two muons and two b quarks, or two muons and two τ leptons. The results are from data in proton-proton collisions corresponding to an integrated luminosity of 19.7 fb−1, accumulated by ...Journal Article -
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 Higgs boson pair production in the bbττ final state in proton-proton collisions at √(s)=8 TeV
(2017)Physical Review DResults are presented from a search for production of Higgs boson pairs (HH) where one boson decays to a pair of b quarks and the other to a τ lepton pair. This work is based on proton-proton collision data collected by the CMS experiment at √s=8 TeV, corresponding to an integrated luminosity of 18.3 fb−1. Resonant and nonresonant modes of HH production have been probed and no significant excess relative to the background-only hypotheses ...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 -

(2017)Journal of High Energy PhysicsA measurement of the cross section for top quark-antiquark (tt¯) pairs produced in association with a photon in proton-proton collisions at s√=8 TeV is presented. The analysis uses data collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 19.7 fb1. The signal is defined as the production of a tt¯ pair in association with a photon having a transverse energy larger than 25 GeV and an absolute pseudorapidity ...Journal Article -

(2017)Physical Review LettersA search for charged Higgs bosons produced via vector boson fusion and decaying into W and Z bosons using proton-proton collisions at root s = 13 TeV is presented. The data sample corresponds to an integrated luminosity of 15.2 fb(-1) collected with the CMS detector in 2015 and 2016. The event selection requires three leptons (electrons or muons), two jets with large pseudorapidity separation and high dijet mass, and missing transverse ...Journal Article
