Measurements of $W^+W^-+\ge 1$ jet production cross-sections in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector / ATLAS Collaboration
Fiducial and differential measurements of $W^+W^-$ production in events with at least one hadronic jet are presented. These cross-section measurements are sensitive to the properties of electroweak-boson self-interactions and provide a test of perturbative quantum chromodynamics and the electroweak theory. [...]

Evidence for Higgs boson decays to a low-mass dilepton system and a photon in pp collisions at $\sqrt{s} =$ 13 TeV with the ATLAS detector / ATLAS Collaboration
A search for the Higgs boson decaying into a photon and a pair of electrons or muons with an invariant mass $m_{\ell\ell} < 30$ GeV is presented. The analysis is performed using 139 fb$^{-1}$ of proton-proton collision data, produced by the LHC at a centre-of-mass energy of 13 TeV and collected by the ATLAS experiment. [...]

Search for new phenomena in events with an energetic jet and missing transverse momentum in $pp$ collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector / ATLAS Collaboration
Results of a search for new physics in final states with an energetic jet and large missing transverse momentum are reported. The search uses proton-proton collision data corresponding to an integrated luminosity of 139 fb$^{-1}$ at a center-of-mass energy of 13 TeV collected in the period 2015-2018 with the ATLAS detector at the Large Hadron Collider.

Muon reconstruction and identification efficiency in ATLAS using the full Run 2 $pp$ collision data set at $\sqrt{s}=13$ TeV / ATLAS Collaboration
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. The increased instantaneous luminosity delivered by the LHC over this period required a reoptimisation of the criteria for the identification of prompt muons. [...]

Search for Single Top Production in $e^{+}e^{-}$ Collisions at $\sqrt{s}$ = 189 - 202 GeV / ALEPH Collaboration
The single top production via flavour changing neutral currents in the reactions ee -> t c/u is searched for in approximately 411 pb-1 of data collected by ALEPH at centre-of-mass energies in the range between 189 and 202 GeV. In total, 58 events are selected in the data to be compared with 50.3 expected from Standard Model backgrounds. [...]

Investigation of Inclusive CP Asymmetries in B$^{0}$ Decays / ALEPH Collaboration
A search for CP violating effects in the mixing of neutral B mesons is performed using a sample of 4.1 million hadronic Z decays collected with the ALEPH detector from 1991 to 1995. By studying time-dependent asymmetries in flavour-tagged samples of semileptonic and fully inclusive b-hadron decays, two measurements of the semileptonic asymmetry a_cp are extracted. [...]

Search for a Scalar Top almost degenerate with the lightest Neutralino in $e^{+}e^{-}$ Collisions at $\sqrt{s}$ up to 202 GeV / ALEPH Collaboration
Data collected at centre-of-mass energies from 189 GeV to 202 GeV by the ALEPH detector at LEP, corresponding to an integrated luminosity of 411 pb-1, are analysed in a search for the scalar top in the decay channels 'stop -> c/u neutralino' for small mass differences between the stop and the lightest neutralino. No evidence for deviations from the Standard Model expectation is found and a lower limit of 59 GeV/c**2 is set for the stop mass, independent of the stop to neutralino mass difference and of the stop lifetime..

Measurement of the W Mass and Width in $e^+ e^-$ Collisions at 189 GeV / ALEPH Collaboration
The mass of the W boson is determined in e+e- collisions at LEP by the direct reconstruction of W decays in WW->qqqq and WW->lvqq events, supplemented by measurements using the kinematic properties of the leptons in the WW->lvlv decay channel. The main sample of W pairs is selected from an integrated luminosity of 174 pb^-1 collected with the ALEPH detector in 1998 at a centre-of-mass energy of 188.63 GeV.The combined result from all channels is mW = 80.432+-0.072(stat.)+-0.041(syst.)+-0.019(FSI)+-0.017(LEP) GeV/c^2, where FSI represents the possible effects of final state interactions in the qqqq channel [...]
