Using the data collected by the L3 experiment at LEP from 1991 to 1995 at energies around the Z mass, a measurement of the weak anomalous magnetic dipole moment, a(tau)(w), and of the weak electric dipole moment, d(tau)(w), of the tau lepton is performed. These quantities are obtained from angular distributions in e(+)e(-)--> tau(+)tau(-)--> h(+)<(nu)over bar>(tau)h(-)nu(tau), where h is a pi or a rho. The results are: Re(a(tau)(w)) = (0.0 +/- 1.6 +/- 2.3) X 10(-3), Im(a(tau)(w)) = (-1.0 +/- 3.6 +/- 4.3) X 10(-3) and Re(d(tau)(w)) = (-0.44 +/- 0.88 +/- 1.33)X 10(-17)e.cm. This is the first direct measurement of a(tau)(w). (C) 1998 Elsevier Science B,V. All rights reserved.

Abstract

Using the data collected by the L3 experiment at LEP from 1991 to 1995 at energies around the Z mass, a measurement of the weak anomalous magnetic dipole moment, a(tau)(w), and of the weak electric dipole moment, d(tau)(w), of the tau lepton is performed. These quantities are obtained from angular distributions in e(+)e(-)--> tau(+)tau(-)--> h(+)<(nu)over bar>(tau)h(-)nu(tau), where h is a pi or a rho. The results are: Re(a(tau)(w)) = (0.0 +/- 1.6 +/- 2.3) X 10(-3), Im(a(tau)(w)) = (-1.0 +/- 3.6 +/- 4.3) X 10(-3) and Re(d(tau)(w)) = (-0.44 +/- 0.88 +/- 1.33)X 10(-17)e.cm. This is the first direct measurement of a(tau)(w). (C) 1998 Elsevier Science B,V. All rights reserved.
