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

Autores: Dova, María Teresa; L3 Collaboration

Tipo de recurso: artículo
Estado: versión publicada
Descripción: 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: $a_{τ} =0.004±0.027±0.023;$ $d_{τ} =(0.0±1.5±1.3)×10^{−16} e· cm .$ . This is a direct measurement of these t form factors at q2=0.
