Search for dark matter particles produced in association with a Higgs boson in proton-proton collisions at s√ = 13 TeV
(Springer Nature, 2020-03-04)
A search for dark matter (DM) particles is performed using events with a Higgs boson candidate and large missing transverse momentum. The analysis is based on proton- proton collision data at a center-of-mass energy of 13 ...
Measurement of top quark pair production in association with a Z boson in proton-proton collisions at s√ = 13 TeV
(Springer Nature, 2020-03-10)
A measurement of the inclusive cross section of top quark pair production in association with a Z boson using proton-proton collisions at a center-of-mass energy of 13 TeV at the LHC is performed. The data sample corresponds ...
Evidence for light-by-light scattering and searches for axion-like particles in ultraperipheral PbPb collisions at √sNN = 5.02 TeV
(Elsevier, 2019-10-10)
Evidence for the light-by-light scattering process, gamma gamma -> gamma gamma, in ultraperipheral PbPb collisions at a centre-of-mass energy per nucleon pair of 5.02 TeV is reported. The analysis is conducted using a data ...
Search for a heavy pseudoscalar boson decaying to a Z and a Higgs boson at √s = 13 TeV
(Springer Nature, 2019-07-03)
A search is presented for a heavy pseudoscalar boson A decaying to a Z boson and a Higgs boson with mass of 125 GeV. In the final state considered, the Higgs boson decays to a bottom quark and antiquark, and the Z boson ...
Searches for Higgs bosons in pp collisions at root s=7 and 8 TeV in the context of four-generation and fermiophobic models
(Elsevier, 2013-08-09)
Searches are reported for Higgs bosons in the context of either the standard model extended to include a fourth generation of fermions (SM4) with masses of up to 600 GeV or fermiophobic models. For the former, results from ...
Study of the mass and spin-parity of the Higgs boson candidate via its decays to Z boson pairs
(American Physical Society, 2013)
A study is presented of the mass and spin-parity of the new boson recently observed at the LHC at a mass near 125 GeV. An integrated luminosity of 17: 3 fb(-1), collected by the CMS experiment in proton-proton collisions ...
Search for Higgs and Z boson decays to J/ψor Ypairs in the four-muon final state in proton-proton collisions at √s=13 TeV
(Elsevier, 2019-10-10)
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=13TeV, collected ...
Erratum: Search for a new scalar resonance decaying to a pair of Z bosons in proton-proton collisions at √s = 13 TeV
(Springer Nature, 2019-03-22)
In both panels of figure 11, the unit of the z axis was mistakenly written as pb when it should have been fb. The corrected versions are shown in figure 1.
Searches for new physics using the t(t)over-bar invariant mass distribution in pp collisions at root s=8 TeV
(American Physical Society, 2013-11-22)
Searches for anomalous top quark-antiquark production are presented, based on pp collisions at root s = 8 TeV. The data, corresponding to an integrated luminosity of 19.7 fb(-1), were collected with the CMS detector at the ...
Search for an exotic decay of the Higgs boson to a pair of light pseudoscalars in the final state of two muons and two τ leptons in proton-proton collisions at s√=13 TeV
(Springer Nature, 2018-11)
A search for exotic Higgs boson decays to light pseudoscalars in the final state of two muons and two τ leptons is performed using proton-proton collision data recorded by the CMS experiment at the LHC at a center-of-mass ...
