Precision measurement of the Z boson invisible width in pp collisions at √s = 13 TeV
(2023) [Artigo de periódico]A precise measurement of the invisible width of the Z boson produced in proton-proton collisions at a center-of-mass energy of 13 TeV is presented using data recorded by the CMS experiment at the LHC, corresponding to an ... -
Search for Higgs and Z boson decays to J/ψ or Y pairs in the four-muon final state in proton-proton collisions at √s=13 TeV
(2019) [Artigo de periódico]A search for decays of the Higgs and Z boson to pairs of J/ψ or Y (nS) (n = 1, 2, 3) mesons, with their subsequent decay to μ+μ- pairs, is presented. The analysis uses data from proton-proton collisions at √s=13 TeV, ... -
Search for Higgs boson decays into Z and J/ψ and for Higgs and Z boson decays into J/ψ or Y pairs in pp collisions at √s = 13 TeV
(2023) [Artigo de periódico]Decays of the Higgs boson into a Z boson and a J/ψ or ψ(2S) meson are searched for in four-lepton final states with the CMS detector at the LHC. A data set of proton-proton collisions corresponding to an integrated luminosity ...
