Search for compressed electroweak SUSY production in final states with two $τ$-leptons in $\sqrt{s} = 13$ and $13.6$ TeV $pp$ collisions with the ATLAS detector

Searches for the production of $τ$-sleptons ($\tildeτ$), charginos ($\tildeχ^{\pm}_1$), and neutralinos ($\tildeχ^0_2$) in events with at least one hadronically decaying $τ$-lepton are presented, targeting compressed mass spectra scenarios. For charginos and neutralinos, the cascade decays producing
