Charm and leptons

One of the major planks in the theoretical model of charm is the weak decay of the charmed quark, predominantly via the strange quark mode. Striking confirmation of this picture, and in particular of the weak decay, comes from the Stanford Linear Accelerator group (SLAC) where the charmed mesons D° and D+, produced in electron–positron interactions (Physics Bulletin August 1976 p340), were studied via their respective decays to (K−π+) and (K−π+π+).
