The decay modeτ→πων τ and second class currents
1981
Predictions of a set of equal-time commutators between first and second class currents for the decayτ→πωντ are discussed. Such experiment should be feasible with the present detectors at SPEAR/PEP and DORIS/PETRA.
Tau neutrino mass from semileptonic decays
1981
The semileptonic three particle decays of the tau provide determinations of the tau neutrino mass. The shift of the maximal energy of the observable final state particles islinear in the neutrino mass. The endpoint energy of the pion and a partially integrated decay rate in τ → πωvτ and τ → πρVτ are sensitive to a neutrino mass smaller than 100 MeV. Thus, the present bound on\(m_{v_\tau } \) can significantly be improved.
Commutators of second-class axial currents with normal weak currents and consequences for particle decays
1981
Second-class weak axial currents are studied in the framework of normal weak and electromagnetic currents. Equal time commutators between normal and abnormal axial currents and the isoscalar electromagnetic current are postulated and their consequences are worked out. A number of predictions for masses, coupling constants and decay properties are derived and are compared to available data.
