Description
This talk summarizes a study of realistic design options for a far detector at the Belle II experiment, dubbed GAZELLE. We have quantified the sensitivity of such a detector to long-lived particles produced in e+e- collisions for three benchmark scenarios: axion-like particles, heavy neutral leptons, and a dark matter scenario with a light scalar. GAZELLE will moderately improve the sensitivity to the couplings of these long-lived particles, compared to the excellent sensitivity of the Belle II detector itself. Our general findings can help to design far detectors at the ILC, FCC-ee or CEPC.
