Just a Taste: Lectures on Flavor Physics

Abstract

We review the flavor structure of the Standard Model and the ways in which the flavor parameters are measured. This is an extended writeup of the tasi 2016 lectures on flavor physics. Earlier versions of these notes were presented at pre-susy 2015 and Cornell University's Physics 7661 course in 2010.

Exotic lepton-flavor violating Higgs decays

“…Spurious symmetries are a powerful tool in flavor physics [55,56]. When ϕ is complex, the interactions respect a spurious global L i − L j symmetry under which the mediator is charged, [ϕ] = −2.…”

TASI 2022 lectures on flavor physics

“…The section 5.5 on the rare B decay anomalies has been updated to reflect the recent experimental results on the lepton flavor universality ratios R K and R K * by LHCb. Other excellent TASI lectures on flavor physics and lectures from other summer schools include [25][26][27][28][29][30][31][32]. Additional useful resources for flavor physics are the Heavy Flavor Averaging Group (HFLAV) [33], which provides regular updates to the world averages of heavy flavor quantities, and the Flavour Lattice Averaging Group (FLAG) [34], which reviews lattice results relevant for flavor physics.…”

A tale of invisibility: constraints on new physics in b → sνν

“…The fact that, at leading order, inclusive hadron decays are equivalent to the underlying partonic processes is seen as a manifestation of the notion of "quark-hadron duality" (see for instance ref. [47] for a review). For semi-leptonic inclusive decays, this enforces integrating out the phase space to a sufficiently large extent which is often referred to as a "smearing procedure".…”
