Measurement of the anomalous magnetic and electric dipole moments of the tau lepton
We analyse e+e−→ττγ events using 100 pb-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...

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: <math><mtext>a</mtext><msub><mi></mi><mn>τ</mn></msub><mtext>=0.004±0.027±0.023;</mtext></math> <math><mtext>d</mtext><msub><mi></mi><mn>τ</mn></msub><mtext>=(0.0±1.5±1.3)×10</mtext><msup><mi></mi><mn>−16</mn></msup><mtext>e·</mtext><mtext>cm</mtext><mtext>.</mtext></math>.
