Searches for direct slepton production in the compressed-mass corridor in $\sqrt{s}=13$ TeV $pp$ collisions with the ATLAS detector
This paper presents searches for the direct pair production of charged light-flavour sleptons, each decaying into a stable neutralino and an associated Standard Model lepton. [...]

Measurement of $W^+W^-$ production cross-section at 13.6 TeV with the CMS experiment / Phor, Saumya (Delhi U.) /CMS Collaboration
The first measurements of $W^{+}W^{-}$ production cross section in proton-proton collisions at a centre-of-mass energy of 13.6 TeV are presented. The data used were recorded with the CMS detector at the LHC in 2022, corresponding to an integrated luminosity of 34.8 fb$^{-1}$. The events are selected by requiring one electron and one muon of opposite charge. The total inclusive $W^+W^-$ cross section is measured to be $125.7 \pm 5.6$~pb, consistent with the standard model predictions. Fiducial cross sections are also reported as a function of the jet multiplicity in the event and compared with different theoretical predictions..

Search for heavy neutral leptons in decays of W bosons using leptonic and semi-leptonic displaced vertices in $\sqrt{s} = 13$ TeV $pp$ collisions with the ATLAS detector
A search is performed for long-lived heavy neutral leptons (HNLs), produced through the decay of a $W$ boson along with a muon or electron. [...]
