Suggestion for measuring the weak dipole moment of tau lepton at Z factory
Source PublicationPHYSICAL REVIEW D
Language英语
AbstractThree new observables for Z factory to measure the weak dipole moment of tau lepton (d(w)(tau)) are proposed. As those observables are employed at LEP-I, the new observables depend on the real and imaginary parts of d(w)(tau) linearly; thus, we calculate the slopes, i.e., the linear coefficients of the dependence, precisely and find that the obtained slopes are much lager than those employed at LEP-I. It means that the signal for the weak dipole moment d(w)(tau) may be enhanced quite a lot if one employs the new observables. Being superior to those at LEP-I, we recommend measuring the weak dipole moment d(w)(tau) in terms of the new observables if reanalyzing the data of LEP-I or doing the measurement at a possible Z factory in the near future.
