Description
Over the last 5 years, there have been increasingly strong hints of something
amiss in flavour physics. Starting with a small anomaly in a rare decay mode of B
mesons, the current status amounts to a coherent set of discrepancies involving
the non universality of decays to different flavour leptons - with a combined
significance of around 5 sigma.
I will review the history of these flavour anomalies, and what we mean by a
coherent EFT explanation. I will introduce meson mixing and lifetimes and how they
are calculated, and then discuss how possible NP models that explain the anomalies
are strongly constrained by these calculations.
