Electromagnetic Calculation of the Quark Mixing Matrix

Many years ago Pierre Ramond suggested using an electromagnetic impedance model to calculate neutrino and quark mixing matrices. Given the long-dreaded desert at the LHC (one Higgs and no SUSY), motivated in no small part by Carlo Rubbia's call for courage in pursuit of the Muon Collider, and with neutrino oscillation in the foreground for both experimentalists and theorists, neutrinos took precedence over quarks in following Pierre's guidance. Serendipity recently intervened, when it was realized that precise amplitudes emerging from the neutrino calculations appeared to be not of neutrinos, but rather the closely related quark mixing. What follows presents details of the quark mixing matrix calculation, and outlines an earlier similar QED calculation of π 0 , η, and η ′ branching ratios.
