$B$-physics anomalies: EFT analyses and simplified models

Abstract

We discuss some theoretical aspects related to the $B$-anomalies, both for the neutral current and the charged current anomalies. A possible combined explanation within an EFT framework as well as an explicit simplified model featuring the $U_1$ leptoquark are discussed. The model gives rise to predictions in other sectors that are experimentally accessible within the next few years.
