Search for Pair Production of Up-Type Vector-Like Quarks and for Four-Top-Quark Events in Final States with Multiple B-Jets with the ATLAS Detector
A search for pair production of up-type vector-like quarks (T) with a significant branching ratio into a top quark and either a Standard Model Higgs boson or a Z boson is presented. The same analysis is also used to search ...
Search for the Standard Model Higgs Boson Produced in Association with Top Quarks and Decaying into a bb̅ Pair in pp Collisions at √s=13 TeV with the ATLAS Detector
A search for the standard model Higgs boson produced in association with a top-quark pair, tt̅ H, is presented. The analysis uses 36.1 fb⁻¹ of pp collision data at √s = 13 TeV collected with the ATLAS detector at the Large ...
Reconstruction of Physics Objects at the Circular Electron Positron Collider with Arbor
After the Higgs discovery, precise measurements of the Higgs properties and the electroweak observables become vital for the experimental particle physics. A powerful Higgs/Z factory, the Circular Electron Positron Collider ...
Search for Flavor-Changing Neutral Currents in Top Quark Decays t → Hc and t → Hu in Multilepton Final States in Proton-Proton Collisions at √s =13 TeV with the ATLAS Detector
Flavor-changing neutral currents are not present in the Standard Model at tree level and are suppressed in loop processes by the unitarity of the Cabibbo-Kobayashi-Maskawa matrix; the corresponding rates for top quark decay ...
Search for the Decay of the Higgs Boson to Charm Quarks with the ATLAS Experiment
A direct search for the standard model Higgs boson decaying to a pair of charm quarks is presented. Associated production of the Higgs and Z bosons, in the decay mode ZH → ℓ⁺ℓ⁻ cc̅ is studied. A data set with an integrated ...
Search for a Heavy Higgs Boson Decaying into a Z Boson and Another Heavy Higgs Boson in the ℓℓbb Final State in pp Collisions at √s=13 TeV with the ATLAS Detector
A search for a heavy neutral Higgs boson, A, decaying into a Z boson and another heavy Higgs boson, H, is performed using a data sample corresponding to an integrated luminosity of 36.1 fb⁻¹ from proton–proton collisions ...
Search for Flavor-Changing Neutral Currents in Top Quark Decays T → Hc and T → Hu in Multilepton Final States in Proton-Proton Collisions at √s =13 TeV with the ATLAS Detector
Flavor-changing neutral currents are not present in the Standard Model at tree level and are suppressed in loop processes by the unitarity of the Cabibbo-Kobayashi-Maskawa matrix; the corresponding rates for top quark decay ...
