Search for Top-Quark Decays t → Hq with 36 fb⁻¹ of pp Collision Data at √s = 13 TeV with the ATLAS Detector
(Springer Verlag, 2019-05-21)
A search for flavour-changing neutral current decays of a top quark into an up-type quark (q = u, c) and the Standard Model Higgs boson, t → Hq, is presented. The search is based on a dataset of pp collisions at s = 13 TeV ...
Search for Long-Lived Neutral Particles in pp Collisions at √s=13 TeV That Decay into Displaced Hadronic Jets in the ATLAS Calorimeter
(Springer New York Llc, 2019-06-07)
This paper describes a search for pairs of neutral, long-lived particles decaying in the ATLAS calorimeter. Long-lived particles occur in many extensions to the Standard Model and may elude searches for new promptly decaying ...
Direct Top-Quark Decay Width Measurement in the tt̅ Lepton+Jets Channel at √s =8 TeV with the ATLAS Experiment
This paper presents a direct measurement of the decay width of the top quark using tt̅ events in the lepton+jets final state. The data sample was collected by the ATLAS detector at the LHC in proton-proton collisions at a ...
