Search for a long-lived spin-0 mediator in transitions at the Belle II experiment

Belle II Collaboration, I. Adachi, K. Adamczyk +411

Additional spin-0 particles appear in many extensions of the standard model. We search for long-lived spin-0 particles in -meson decays mediated by a quark transiti…
