Search for physics beyond the standard model in top quark production with additional leptons in the context of effective field theory
(2023)Journal of High Energy PhysicsA search for new physics in top quark production with additional fnal-state leptons is performed using data collected by the CMS experiment in proton-proton collisions at √ s = 13 TeV at the LHC during 2016–2018. The data set corresponds to an integrated luminosity of 138 fb−1 . Using the framework of efective feld theory (EFT), potential new physics efects are parametrized in terms of 26 dimension-six EFT operators. The impacts of EFT ...Journal Article -

Measurement of the t¯t production cross section in pp collisions at √s=7 TeV in dilepton final states containing a τ
(2012)Physical Review DThe top quark pair production cross section is measured in dilepton events with one electron or muon, and one hadronically decaying τ lepton from the decay t¯t→(ℓνℓ)(τhντ)b¯b, (ℓ=e,μ). The data sample corresponds to an integrated luminosity of 2.0 fb−1 for the electron channel and 2.2 fb−1 for the muon channel, collected by the CMS detector at the LHC. This is the first measurement of the t¯t cross section explicitly including τ leptons ...Journal Article -
Measurement of the integrated and differential t¯t production cross sections for high-pT top quarks in pp collisions at √s=8 TeV
(2016)Physical Review DThe cross section for pair production of top quarks (t¯t) with high transverse momenta is measured in pp collisions, collected with the CMS detector at the LHC with √s=8 TeV in data corresponding to an integrated luminosity of 19.7 fb−1. The measurement is performed using lepton+jets events, where one top quark decays semileptonically, while the second top quark decays to a hadronic final state. The hadronic decay is reconstructed as a ...Journal Article -
