Erratum to: Measurement of the W boson polarisation in t t ¯ events from pp collisions at √ s = 8 TeV in the lepton + jets channel with ATLAS (The European Physical Journal C, (2017), 77, 4, (264), 10.1140/epjc/s10052-017-4819-4)

TL;DR: This change does not have any impact on the measured helicity fractions, but it changes the obtained limits on the anomalous couplings as mentioned in this paper, which is a change that has been made for the benefit of the ATLAS collaboration.
Journal ArticleDOI

Search for long-lived charginos based on a disappearing-track signature using 136 fb$$^{-1}$$ of pp collisions at $$\sqrt{s}$$ = 13 TeV with the ATLAS detector

Georges Aad, +2819 more
TL;DR: In this paper , a search for long-lived charginos produced either directly or in the cascade decay of heavy prompt gluino states is presented, based on proton-proton collision data collected at a centre-of-mass energy of 13 TeV between 2015 and 2018 with the ATLAS detector at the LHC, corresponding to an integrated luminosity of 136 fb$^{-1}$.
Journal ArticleDOI

Measurement of KS0 and Λ production in tt¯ dileptonic events in pp collisions at √s= 7 TeV with the ATLAS detector

Georges Aad, +2973 more
- 17 Dec 2019 - 
TL;DR: In this paper, measurements of K-S and Lambda production in tt final states have been performed based on a data sample with integrated luminosity of 4.6 fb(-1) from proton-proton collisions at a c...

Search for R-parity-violating supersymmetry in a final state containing leptons and many jets with the ATLAS experiment using $$\sqrt{s} = 13\hbox { TeV}$$ s = 13 TeV proton–proton collision data

Georges Aad, +2926 more
- 29 Jun 2021 - 
TL;DR: In this article, a search for R-parity-violating supersymmetry in final states characterized by high jet multiplicity, at least one isolated light lepton and either zero or at least three b-tagged jets is presented.
Journal ArticleDOI
