Search for doubly charged Higgs boson production in multi-lepton final states using 139 fb$^{−1}$ of proton-proton collisions at $\sqrt{s}$ = 13 TeV with the ATLAS detector

Georges Aad, +2811 more
TL;DR: In this article , a search for pair production of doubly charged Higgs bosons with the same electric charge is presented, using a proton-proton collision data sample at a centre-of-mass energy of 13 TeV corresponding to an integrated luminosity of 139
Journal ArticleDOI

- 27 Jun 2023 - 
TL;DR: In this paper , a measurement of single top-quark production in the s-channel is performed in proton$-$proton collisions at a centre-of-mass energy of 13 TeV with the ATLAS detector at the CERN Large Hadron Collider.

Search for direct pair production of a chargino and a neutralino decaying to the 125 GeV Higgs boson in √s = 8 TeV pp collisions with the ATLAS detector

Georges Aad, +2809 more
TL;DR: In this paper, a search for the direct pair production of a chargino and a neutralino was presented, where the chargino decayed to the lightest neutralino and the W boson, and the neutralino to the 125 GeV Higgs boson.
