ϒ(nS) polarizations versus particle multiplicity in pp collisions at s=7 TeV
(2016-10-10)
The polarizations of the ϒ(1S), ϒ(2S), and ϒ(3S) mesons are measured as a function of the charged particle multiplicity in proton–proton collisions at s=7 TeV. The measurements are performed with a dimuon data sample ...
Study of Z boson production in pPb collisions at √sNN=5.02 TeV
(2016-08-10)
The production of Z bosons in pPb collisions at sNN=5.02 TeV is studied by the CMS experiment via the electron and muon decay channels. The inclusive cross section is compared to pp collision predictions, and found to scale ...
Inclusive search for supersymmetry using razor variables in pp collisions at s =13 TeV
(2017-01-06)
An inclusive search for supersymmetry using razor variables is performed in events with four or more jets and no more than one lepton. The results are based on a sample of proton-proton collisions corresponding to an ...
Evidence for exclusive γγ → W+ W− production and constraints on anomalous quartic gauge couplings in pp collisions at √s = 7 and 8 TeV
(2016-08-22)
A search for exclusive or quasi-exclusive γγ → W+W− production, via pp → p(*)W+W−p(*) → p(*)μ±e∓p(*) at √s = 8 TeV, is reported using data corresponding to an integrated luminosity of 19.7 fb−1. Events are selected by ...
Search for high-mass diphoton resonances in proton–proton collisions at 13 TeV and combination with 8 TeV search
(2017-05-10)
A search for the resonant production of high-mass photon pairs is presented. The search focuses on spin-0 and spin-2 resonances with masses between 0.5 and 4.5 TeV, and with widths, relative to the mass, between 1.4×10−4 ...
Search for Dark Matter and Supersymmetry with a Compressed Mass Spectrum in the Vector Boson Fusion Topology in Proton-Proton Collisions at s =8 TeV
(2017-01-12)
A first search for pair production of dark matter candidates through vector boson fusion in proton-proton collisions at s=8 TeV is performed with the CMS detector. The vector boson fusion topology enhances missing transverse ...
Measurement of the mass of the top quark in decays with a J/ψ meson in pp collisions at 8 TeV
(2016-12-22)
A first measurement of the top quark mass in the decay channel t → (W → ℓν) (b → J/ψ + X → μ+μ− + X) is presented. The analysis uses events selected from the proton-proton collisions recorded by the CMS detector at the LHC ...
Search for heavy resonances decaying to tau lepton pairs in proton-proton collisions at √s=13 TeV
(2017-02-09)
A search for heavy resonances that decay to tau lepton pairs is performed using proton-proton collisions at s=13 TeV. The data were collected with the CMS detector at the CERN LHC and correspond to an integrated luminosity ...
Measurements of differential cross sections for associated production of a W boson and jets in proton-proton collisions at s =8 TeV
