Study of Z boson plus jets events using variables sensitive to double-parton scattering in pp collisions at 13 TeV
(Springer Verlag, 2021)
Double-parton scattering is investigated using events with a Z boson and jets. The Z boson is reconstructed using only the dimuon channel. The measurements are performed with proton-proton collision data recorded by the ...
Measurement of prompt open-charm production cross sections in proton-proton collisions at √s = 13 TeV
(Springer Science and Business Media Deutschland GmbH, 2021)
The production cross sections for prompt open-charm mesons in proton-proton collisions at a center-of-mass energy of 13 TeV are reported. The measurement is performed using a data sample collected by the CMS experiment ...
Measurements of angular distance and momentum ratio distributions in three-jet and Z + two-jet final states in pp collisions
(Springer Verlag, 2021)
Collinear (small-angle) and large-angle, as well as soft and hard radiations are investigated in three-jet and Z + two-jet events collected in proton-proton collisions at the LHC. The normalized production cross sections ...
Observation of tW production in the single-lepton channel in pp collisions at root s=13 TeV
(Springer Verlag, 2021)
A measurement of the cross section of the associated production of a single top quark and a W boson in final states with a muon or electron and jets in proton-proton collisions at root s = 13 TeV is presented. The data ...
Measurements of the Electroweak Diboson Production Cross Sections in Proton-Proton Collisions at s =5.02 TeV Using Leptonic Decays
(American Physical Society, 2021)
The first measurements of diboson production cross sections in proton-proton interactions at a center-of-mass energy of 5.02 TeV are reported. They are based on data collected with the CMS detector at the LHC, corresponding ...
Performance of the CMS muon trigger system in proton-proton collisions at √s = 13 TeV
(IOP Publishing, 2021)
The muon trigger system of the CMS experiment uses a combination of hardware and software to identify events containing a muon. During Run 2 (covering 2015-2018) the LHC achieved instantaneous luminosities as high as 2 × ...
Measurement of the Wγ production cross section in proton-proton collisions at √ s = 13 TeV and constraints on effective field theory coefficients
(American Physical Society, 2021)
A fiducial cross section for Wγ production in proton-proton collisions is measured ata center-of-mass energy of 13 TeV in 137 fb−1 of data collected using the CMS detector at the LHC. The W → eν and µν decay modes are used ...
Observation of a New Excited Beauty Strange Baryon Decaying to Ξ− b π + π −
(American Physical Society, 2021)
The Ξb-π+π- invariant mass spectrum is investigated with an event sample of proton-proton collisions at s=13 TeV, collected by the CMS experiment at the LHC in 2016-2018 and corresponding to an integrated luminosity of 140 ...
Measurements of production cross sections of the Higgs boson in the four-lepton final state in proton-proton collisions at √ s = 13 TeV
