This paper reports a search for decays of long-lived charginos or $\tau$-sleptons to final states containing a short disappearing track, a single high-energy jet, and missing transverse momentum. The search uses 137 fb$^{-1}$ of data from 13 TeV proton-proton collisions recorded by …

This project concerns the simulation, development and evaluation of monolithic fine-pitch pixel sensors implemented in the TPSCo65 process, targeting the vertex-detector requirements of future Lepton Colliders as outlined in the ECFA detector roadmap. Key final development goals include 3 µm single-point resolution, …

A measurement of correction factors for the hadronic jet energy scale and resolution in the ATLAS detector is presented. These correction factors account for differences between simulated and observed data. They are obtained by analysing a selection of top quark events collected …
