As part of an ongoing effort to understand the source of the discrepancy between data-driven and lattice determinations of the HVP contribution to a_mu, the anomalous magnetic moment of the muon, we perform data-driven determinations of the light-quark-connected and strange-plus-disconnected contributions to a number of "window" contributions to a_mu, including the RBC/UKQCD intermediate...
We compute for the first time the τ data-driven Euclidean windows for the hadronic vacuum polarization contribution to the muon g−2. We show that τ-based results agree with the available lattice window evaluations and with the full result. On the intermediate window, where all lattice evaluations are rather precise and agree, τ-based results are compatible with them. This is particularly...
Precise measurements of magnetic and electric dipole moments are important tests of the standard model and beyond standard model physics, in particular for the electron and the muon. However, when dealing with the tau lepton, the situation presents distinctive challenges due to its very short lifetime and relatively high mass. In this talk, we review the theoretical predictions and the...
The electric dipole moment (EDM) of the tau lepton is a good probe for new physics. The measurement has been and will be performed based on the huge amount of tau-pair production data collected with the high-luminosity colliders. The status of the measurement and prospects for future experiment will be presented.
