Theoretical point of view on Cabibbo angle anomaly
- Teppei Kitahara
International Journal of Modern Physics A24 Aug 2024
Preview Abstract
In this paper, we present the current situation of the determinations of the first-row CKM components and show the Cabibbo angle anomaly corresponding to a deficit in the first-row CKM unitarity condition at the $3 σ$ level. In this contribution, we show two new physics interpretations: heavy vector-like quark models and a MeV scale sterile neutrino scenario. The super tau-charm facility will directly probe the other CKM unitarity conditions related to $V_{c d}$ .
