Flavour bounds on axions, hidden photons and sterile neutrinos
arXiv:2404.01095
Abstract
Flavour-violating decays are some of the most sensitive probes for New Physics with masses below the B meson threshold. In this talk I review the sensitivity to axion-like particles, hidden photons and heavy neutral leptons assuming minimal models where these are the only particle in addition to the Standard Model, respectively.
