Dark matter summary plots for $s$-channel, 2HDM+$a$, Higgs portal and Dark Higgs models
This note presents summary plots for dark matter simplified models with $s$-channel spin-1 and spin-0 mediators, a Two-Higgs-Doublet model with an extra pseudoscalar mediator (2HDM+$a$), Higgs portal models and a Dark Higgs model. [...]

Limits on long-lived chargino production using large specific ionisation and low-$\beta$ in $140\;\text{fb}^{-1}$ of $pp$ collisions at $\sqrt{s} = 13\;\text{TeV}$ using the ATLAS experiment
This note reinterprets a search utilising large specific ionisation in the pixel detector and the time-of-flight to the hadron calorimeter of the ATLAS detector at the LHC using an integrated luminosity of $140\;\text{fb}^{-1}$ of proton-proton collisions at $\sqrt{s} = 13\;\text{TeV}$. [...]

Summary plots for beyond Standard Model Higgs boson benchmarks for direct and indirect searches
This note presents an update of the plots that summarize the interpretations of various searches for additional Higgs bosons beyond the Standard Model, as well as the Higgs boson coupling combination, in the hMSSM and the 2HDM. [...]

Reinterpretation of electroweak supersymmetry searches with final states containing taus in models of variable $R$-parity-violating coupling strength
Two ATLAS searches for supersymmetric particles in final states with multiple leptons, optimized for $R$-parity-conserving and $R$-parity-violating models, are reinterpreted in models with variable $R$-parity-violating couplings. [...]
