Journal ArticleDOI

A measurement of the product branching ratio f(b → Λb) · BR(Λb → ΛX) in Z0 decays

Giovanni Abbiendi, +342 more
- 01 Jan 1999 - 
TL;DR: In this paper, the product branching ratio was measured using the OPAL detector at LEP, where the presence of energetic Lambda particles in bottom events was identified by the displacement of displaced secondary vertices.
Journal ArticleDOI

Search for Higgs Boson Decays into a Z Boson and a Light Hadronically Decaying Resonance Using 13 TeV pp Collision Data from the ATLAS Detector

Georges Aad, +2945 more
- 25 Nov 2020 - 
TL;DR: A search for Higgs boson decays into a Z boson and a light resonance in two-lepton plus jet events is performed, using a pp collision dataset with an integrated luminosity of 139 fb^{-1} collected by the ATLAS experiment at the CERN LHC.
Journal ArticleDOI

Measurement of charged-particle event shape variables in inclusive √(s)=7 TeV proton-proton interactions with the ATLAS detector

Georges Aad, +2881 more
- 06 Aug 2013 - 
TL;DR: In this article, the authors measured the transverse thrust, thrust minor, and transverse sphericity of charged particle collisions at a center-of-mass energy of 7 TeV using the ATLAS detector at the LHC.
Journal ArticleDOI

Measurement of the correlation between the polar angles of leptons from top quark decays in the helicity basis at s =7 T e V using the ATLAS detector

Georges Aad, +2857 more
- 13 Jan 2016 - 
TL;DR: In this article, a measurement of the correlations between the polar angles of leptons from the decay of pair-produced t and (t) over bar quarks in the helicity basis is reported, using proton-proton collision data collected by the ATLAS detector at the LHC.
Journal ArticleDOI

Direct top-quark decay width measurement in the tt¯ lepton+jets channel at √s=8TeV with the ATLAS experiment

Morad Aaboud, +2886 more
- 15 Feb 2018 - 
TL;DR: The decay width of the top quark is measured using a template fit to distributions of kinematic observables associated with the hadronically and semileptonically decaying top quarks and is consistent with the prediction of the Standard Model.
