Improved Bounds on the Electromagnetic Dipole Moments of the Tau Lepton
نویسنده
چکیده
Using electroweak data and an effective Lagrangian approach we obtain stringent bounds on the tau anomalous magnetic moment, −0.004 ≤ aτ ≤ 0.006, and on its electric dipole moment, |dτ | ≤ 1.1× 10 e cm. This significantly improves our previous bounds. With the same method, we obtain limits on the dipole moments of other fermions. ∗Laboratoire associé au C.N.R.S. — URA D0063.

Model independent bounds on the tau lepton electromagnetic and weak magnetic moments
Using LEP1, SLD and LEP2 data, for tau lepton production, and data from pp̄ colliders and LEP2, for W decays into tau leptons, we set model independent limits on non-standard electromagnetic and weak magnetic moments of the tau lepton. The most general effective Lagrangian giving rise to tau moments is used without further assumptions. Precise bounds (2σ) on the non-standard model contributions ...
متن کاملBounds on the Tau Magnetic Moments: Standard Model and Beyond
We obtain new bounds for the magnetic dipole moments of the tau lepton. These limits on the magnetic couplings of the tau to the electroweak gauge bosons (γ,W,Z) are set in a model independent way using the most general effective Lagrangian with the SU(2)L ⊗ U(1)Y symmetry. Comparison with data from the most precise experiments at high energies shows that the present limits are more stringent t...
متن کاملRadiative Tau Lepton Pair Production as a Probe of Anomalous Electromagnetic Couplings of the Tau
We calculate the squared matrix element for the process ee → ττγ allowing for anomalous magnetic and electric dipole moments at the ττγ vertex. No interferences are neglected and no approximations of light fermion masses are made. We show that anomalous moments affect not only the cross section, but also the shape of the photon energy and angular distributions. We also demonstrate that in the c...
متن کاملAnomalous magnetic and electric moments of τ and lepton flavor mixing matrix in effective lagrangian approach
In an effective lagrangian approach [1] to new physics, the authors in ref. [2] pushed tau anomalous magnetic and electric dipole moments (AMDM and EDM) down to 10−11 and 10−25 e cm by using a Fritzsch-Xing lepton mass matrix ansatz. In this note, we find that, in this approach, there exists the connection between τ AMDM and EDM and the lepton flavor mixing matrix. By using the current neutrino...
متن کاملAnomalous Magnetic and Electric Dipole Moments of the Tau
This paper reviews the theoretical predictions for and the experimental measurements of the anomalous magnetic and electric dipole moments of the tau lepton. In particular, recent analyses of the ee → ττγ process from the L3 and OPAL collaborations are described. The most precise results, from L3, for the anomalous magnetic and electric dipole moments respectively are: aτ = 0.004 ± 0.027 ± 0.02...
