Review of neutral naturalness
The hierarchy between the mass of the Higgs boson and larger mass scales becomes ever
more puzzling as experiments push to higher energies. Neutral naturalness is the umbrella …

Near or far detectors? A case study for long-lived particle searches at electron-positron colliders
R Schäfer, F Tillinger, S Westhoff - Physical Review D, 2023 - APS
We explore the discovery potential for long-lived particles at the 250-GeV ILC. The goal is to
investigate possible gains of a dedicated far detector over the main detector ILD. For …
