Bottom quarks 18 pp. (1984).
Recent results on weak interactions from experiments at the PETRA e+e− storage ring are presented. They include the determination of the weak neutral couplings in the purely leptonic reactions e+e−→e+e−, e+e−→μ+μ− and e+e− →τ+τ− and in the production of heavy charm and bottom quarks e+e−→cc̄ and e+e−→bb̄. The weak charged current is tested in τ decays, where new data on semihadronic branching ratis and a new lifetime measurement is reported, and in semileptonic decays of charm and bottom quarks. |
