Search for R-parity violating supersymmetry in pp collisions at √s=13TeV using b jets in a final state with a single lepton, many jets, and high sum of large-radius jet masses
(2018)Physics Letters BResults are reported from a search for physics beyond the standard model in proton–proton collisions at a center-of-mass energy of s=13TeV. The search uses a signature of a single lepton, large jet and bottom quark jet multiplicities, and high sum of large-radius jet masses, without any requirement on the missing transverse momentum in an event. The data sample corresponds to an integrated luminosity of 35.9 fb−1 recorded by the CMS ...Journal Article -
Nuclear modification factor of D0 mesons in PbPb collisions at 𝑠NN‾‾‾‾√=5.02 TeV
(2018)Physics Letters BThe transverse momentum (pT) spectrum of prompt D0 mesons and their antiparticles has been measured via the hadronic decay channels D0 -> K-π+ and D0 -> K+π- in pp and PbPb collisions at a centre-of-mass energy of 5.02 TeV per nucleon pair with the CMS detector at the LHC. The measurement is performed in the D0 meson range of 2–100 GeV/c and in the rapidity range of y < 1 . The pp(PbPb) dataset used for this analysis corresponds to an ...Journal Article -
Azimuthal correlations for inclusive 2-jet, 3-jet, and 4-jet events in pp collisions at √s=13 TeV
(2018)The European Physical Journal CAzimuthal correlations between the two jets with the largest transverse momenta pT in inclusive 2-, 3-, and 4-jet events are presented for several regions of the leading jet pT up to 4TeV. For 3- and 4-jet scenarios, measurements of the minimum azimuthal angles between any two of the three or four leading pT jets are also presented. The analysis is based on data from proton–proton collisions collected by the CMS Collaboration at a ...Journal Article -
Search for a heavy resonance decaying into a Z boson and a vector boson in the νν¯qq¯ final state
(2018)Journal of High Energy PhysicsA search is presented for a heavy resonance decaying into either a pair of Z bosons or a Z boson and a W boson (ZZ or WZ), with a Z boson decaying into a pair of neutrinos and the other boson decaying hadronically into two collimated quarks that are reconstructed as a highly energetic large-cone jet. The search is performed using the data collected with the CMS detector at the CERN LHC during 2016 in proton-proton collisions at a ...Journal Article -
Measurement of the inelastic proton-proton cross section at √s=13 TeV
(2018)Journal of High Energy PhysicsA measurement of the inelastic proton-proton cross section with the CMS detector at a center-of-mass energy of s√=13 TeV is presented. The analysis is based on events with energy deposits in the forward calorimeters, which cover pseudorapidities of −6.6 < η < −3.0 and +3.0 < η < +5.2. An inelastic cross section of 68.6 ± 0.5(syst) ± 1.6(lumi) mb is obtained for events with MX > 4.1 GeV and/or MY > 13 GeV, where MX and MY are the masses ...Journal Article -
Measurement of the underlying event activity in inclusive Z boson production in proton-proton collisions at √s=13 TeV
(2018)Journal of High Energy PhysicsThis paper presents a measurement of the underlying event activity in proton-proton collisions at a center-of-mass energy of 13 TeV, performed using inclusive Z boson production events collected with the CMS experiment at the LHC. The analyzed data correspond to an integrated luminosity of 2.1 fb−1. The underlying event activity is quantified in terms of the charged particle multiplicity, as well as of the scalar sum of the charged ...Journal Article -
Search for a new scalar resonance decaying to a pair of Z bosons in proton-proton collisions at √s=13 TeV
(2018)Journal of High Energy PhysicsA search for a new scalar resonance decaying to a pair of Z bosons is performed in the mass range from 130 GeV to 3 TeV, and for various width scenarios. The analysis is based on proton-proton collisions recorded by the CMS experiment at the LHC in 2016, corresponding to an integrated luminosity of 35.9 fb−1 at a center-of-mass energy of 13 TeV. The Z boson pair decays are reconstructed using the 4ℓ, 2ℓ2q, and 2ℓ2ν final states, where ℓ ...Journal Article -
