We have studied three realistic benchmark geometries for a new far detector GAZELLE to search for long-lived particles at the SuperKEKB accelerator in Tsukuba, Japan. The new detector would be housed in the same building as Belle II and observe the same e+e− collisions. To assess the discovery reach of GAZELLE, we have investigated three new physics models that predict long-lived particles: heavy neutral leptons produced in tau lepton decays, axion-like particles produced in B meson decays, and… Expand
