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. I then present new results discussing their mathematical properties and show a new, and much simpler, method to derive them that takes advantage of these properties.
