Measurement of the semileptonic t t ¯ + γ production cross section in pp collisions at √s=8 TeV
(Springer International Publishing, 2017-10-02)
A measurement of the cross section for top quark-antiquark ( tt¯tt¯ ) pairs produced in association with a photon in proton-proton collisions at s√=8s=8 TeV is presented. The analysis uses data collected with the CMS ...
Search for new physics in top quark production with additional leptons in proton-proton collisions at s√ = 13 TeV using effective field theory
(Springer, 2021-03-09)
Events containing one or more top quarks produced with additional prompt leptons are used to search for new physics within the framework of an effective field theory (EFT). The data correspond to an integrated luminosity ...
Measurement of the top quark mass using events with a single reconstructed top quark in pp collisions at √s = 13 TeV
(Springer, 2021-12-21)
A measurement of the top quark mass is performed using a data sample enriched with single top quark events produced in the t channel. The study is based on proton- proton collision data, corresponding to an integrated ...
Measurement of the inclusive and differential t t¯ γ cross sections in the single-lepton channel and EFT interpretation at √s = 13 TeV
(Springer, 2021-12-23)
The production cross section of a top quark pair in association with a photon is measured in proton-proton collisions at a center-of-mass energy of 13 TeV. The data set, corresponding to an integrated luminosity of 137 ...
Probing effective field theory operators in the associated production of top quarks with a Z boson in multilepton final states at s√ = 13 TeV
(Springer, 2021-12-13)
A search for new top quark interactions is performed within the framework of an effective field theory using the associated production of either one or two top quarks with a Z boson in multilepton final states. The data ...
Observation of tW production in the single-lepton channel in pp collisions at s√ = 13 TeV
(Springer, 2021-11-11)
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 s = 13 TeV is presented. The data correspond ...
Combination of the W boson polarization measurements in top quark decays using ATLAS and CMS data at √s = 8 TeV
(Springer, 2020-08-12)
The combination of measurements of the W boson polarization in top quark decays performed by the ATLAS and CMS collaborations is presented. The measurements are based on proton-proton collision data produced at the LHC at ...
Search for top quark decays via Higgs-boson-mediated flavor-changing neutral currents in pp collisions at root √s = 8 TeV
(Springer International Publishing, 2017-02-15)
A search is performed for Higgs-boson-mediated flavor-changing neutral currents in the decays of top quarks. The search is based on proton-proton collision data corresponding to an integrated luminosity of 19.7 fb(-1) at ...
