Improved Bounds on the Electromagnetic Dipole Moments of the Tau Lepton

Abstract

Using electroweak data and an effective Lagrangian approach we obtain stringent bounds on the tau anomalous magnetic moment, $-0.004\le a_{\tau }\le 0.006$, and on its electric dipole moment, $|d_{\tau }|\le 1.1\times 10^{-17}e$ cm. This significantly improves our previous bounds. With the same method, we obtain limits on the dipole moments of other fermions.
