Professor Yuval Grossman is 2021/2022 Sackler lecturer of the Mortimer and Raymond Sackler Institute of Advanced Studies.
Abstract:
The approximate symmetries of QCD: isospin, U-spin, and flavor SU(3), played a major role in our understanding of the SM. They are still used today as a lot of more data are coming from LHSCb and Belle-2. In this talk, I will review their use and how they were traditionally found. Then, I move to show new results, discuss their mathematical properties and show a new, and much simpler, method to derive the sum rules that takes advantage of these properties.
