Measurement of the anomalous magnetic and electric dipole moments of the tau lepton

Measurement of the anomalous magnetic and electric dipole moments of the tau lepton

We analyse e+e-→ ττγ events using 100pb-1 of data collected by the L3 experiment during the 1991-1995 LEP runs at the Z pole. From the energy of the photons and their isolation from the tau decay products, we determine the anomalous magnetic and electric dipole moments of the tau to be, respectively...
