Search for higgsinos in compressed mass spectra using low-momentum tracks in pp collisions at s = 13 $$ \sqrt{s}=13 $$ TeV with the ATLAS detector

open access: yesJournal of High Energy Physics
This paper presents two searches for the electroweak production of higgsinos with compressed mass spectra using 140 fb −1 of s = 13 $$ \sqrt{s}=13 $$ TeV proton-proton collision data collected by the ATLAS experiment at the Large Hadron Collider.

Measurement of the |V cb | element of the CKM matrix in t t ¯ $$ t\overline{t} $$ decays with the ATLAS detector

open access: yesJournal of High Energy Physics
The first measurement of the magnitude of the CKM quark mixing matrix element |V cb | using on-shell W-boson decays is presented. The measurement is made with t t ¯ $$ t\overline{t} $$ events from pp collision data corresponding to an integrated ...

Search for a resonance decaying into a scalar particle and a Higgs boson in the final state with two bottom quarks and two photons in proton–proton collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics
A search for the resonant production of a heavy scalar X decaying into a Higgs boson and a new lighter scalar S, through the process X → S(→ b b ¯ $$ b\overline{b} $$ )H(→γγ), where the two photons are consistent with the Higgs boson decay, is performed.
