I show that the electric dipole moment of the W-boson vanishes to two loop order in the Standard KM model. As a consequence, the electric dipole moment of the electron vanishes to three loop order. Including QCD corrections may give a non-vanishing result; I estimate d_W \approx 8 10^-31 ecm which induces an electron EDM \approx 8 10^-41 ecm, considerably smaller found in a previous calculation.

  1. Sensitivity Study of the Tau Lepton Electric Dipole Moment at the Super Tau-Charm Facility

    hep-ex 2024-11 conditional novelty 5.0 of 10

    With optimized selection and an optimal observable, STCF could reach |d_tau| below 3.9e-18 e cm at 68% confidence, improving the Belle limit by about a factor of three.

  2. CP violation studies at Super Tau-Charm Facility

    hep-ex 2025-02 conditional novelty 4.0 of 10

    A future Super Tau-Charm Facility is projected to test CP violation in hyperon, tau, and charm decays at 1e-4 to 1e-3 sensitivities and improve the kaon CPT mass-difference limit tenfold.

  3. Searches for exotic spin-dependent interactions with spin sensors

    quant-ph 2024-12 unverdicted

    A review article that compiles how spin-based quantum sensors search for beyond-Standard-Model spin-dependent interactions, without adding new measurements.
