| 英文摘要 | We have analysed the e(+)e(-) collision data collected with Beijing Spectrometer at the center-of-mass energy 4.03 GeV and selected e(+)e(-) --> tau(+/-)tau(-/+) e(+/-)X(-/+) nu's events, X+/- required as mu(+/-), pi(+/-) and rho(+/-). From fitting electron energy spectrum in tau --> e nu's decay, the measurement value of Michel parameter is given as rho(tau --> e) 0.705(-0.054-0.026)(+0.055+0.027), this result is in good agreement with the prediction of standard Model. |
