Description
Flavourful Feebly-Interacting Particles (FIPs) in the MeV to GeV range have a strong impact on precision frontier observables ranging from rare meson decays to the lepton anomalous magnetic moments. We use an effective field theory approach “SM+X” along with the HEPfit package to study the effect of FIPs on B to K observables. We present an updated study of the available parameter space and constraints, focusing on FIP scenarios allowing for a simultaneous fit of both the $R_{K^{(*)}}$ and the $(g-2)_{\mu}$ anomalies. We further present an explicit UV realization.
