Sterile Neutrinos for Flavor Anomalies
Abstract
We discuss interpretations of anomalies in semitauonic to light semileptonic B decay ratios, R (D (*)), in frameworks where new physics couples to a light right-handed neutrino. An EFT level discussion of all simplified models involving a right-handed neutrino that can give rise to the relevant decay channel is presented. We discuss in detail the phenomenology of these flavor anomalies-inspired light sterile neutrinos, which includes possibilities for displaced decays at colliders and direct searches, measurable dark radiation, and gamma ray signals.
