Muon reconstruction and identification efficiency in ATLAS using the full Run 2 $pp$ collision data set at $\sqrt{s}=13$ TeV
This article documents the muon reconstruction and identification efficiency obtained by the ATLAS experiment for 139 fb$^{-1}$ of $pp$ collision data at $\sqrt{s}=13$ TeV collected between 2015 and 2018 during Run 2 of the LHC [...]

Topping-up multilepton plus b-jets anomalies at the LHC with a $Z'$ boson / Alvarez, Ezequiel (ICAS, UNSAM, Buenos Aires ; San Martin Natl. U. ; Buenos Aires, CONICET) ; Juste, Aurelio (Barcelona, IFAE ; ICREA, Barcelona) ; Szewc, Manuel (ICAS, UNSAM, Buenos Aires ; San Martin Natl. U. ; Buenos Aires, CONICET) ; Vazquez Schroeder, Tamara (CERN)
During the last years ATLAS and CMS have reported a number of slight to mild discrepancies in signatures of multileptons plus $b$-jets in analyses such as $t\bar t H$, $t\bar t W^\pm$, $t\bar t Z$ and $t\bar t t\bar t$. [...]

Experience and performance of persistent memory for the DUNE data acquisition system / Abed Abud, Adam (Liverpool U. ; CERN) ; Lehmann, Giovanna (CERN) ; Sipos, Roland (CERN)
Emerging high-performance storage technologies are opening up the possibility of designing new distributed data acquisition system architectures, in which the live acquisition of data and their processing are decoupled through a storage element. [...]

T2K measurements of muon neutrino and antineutrino disappearance using $3.13\times 10^{21}$ protons on target / T2K Collaboration
We report measurements by the T2K experiment of the parameters $\theta_23$ and $\Delta m^2_{32}$ which govern the disappearance of muon neutrinos and antineutrinos in the three-flavor PMNSneutrino oscillation model at T2K's neutrino energy and propagation distance. [...]

Observation of the $\varLambda^{0}_{b}\to\varLambda^{+}_{c}K^{+}K^{-}\pi^{-}$ decay / LHCb Collaboration
The $\varLambda^{0}_{b}\to\varLambda^{+}_{c}K^{+}K^{-}\pi^{-}$ decay is observed for the first time using a data sample of proton-proton collisions at centre-of-mass energies of $\sqrt{s}=7$ and 8 $\rm{TeV}$ collected by the $\mbox{LHCb}$ detector, corresponding to an integrated luminosity of $3{\rm{fb}^{-1}}$.
