$\tau$ electric Dipole Moment with polarized beams
arXiv: High Energy Physics - Phenomenology, 2007Co-Authors: G. A. González-sprinberg, J Bernabeu, J. VidalAbstract:High luminosity Super B/Flavor factories, near and on top of the $\Upsilon$ resonances, allow for a detailed investigation of CP-violation in $\tau$ physics. In particular, bounds on the $\tau$ electric Dipole Moment can be obtained from CP-odd observables. We perform an independent analysis from other low and high energy data. For polarized electron beam a CP-odd asymmetry, associated to the normal polarization term, can be used to set stringent bounds on the $\tau$ electric Dipole Moment.

the tau weak magnetic Dipole Moment
Nuclear Physics, 1995Co-Authors: J Bernabeu, G A Gonzalezsprinberg, Michael M Tung, J. VidalAbstract:Abstract We calculate the prediction for the anomalous weak-magnetic form factor of the tau lepton at q 2 = M 2 within the Standard Model. With all particles on-shell, this is an electroweak gauge-invariant quantity. Its value is a τ w ( M Z 2 )= − (2.10+0.61 i ) × 10 −6 . We show that the transverse and normal components of the single-tau polarization of tau pairs produced at e + e − unpolarized collisions are sensitive to the real and absorptive parts of the anomalous weak-magnetic Dipole Moment of the tau. The sensitivity one can achieve at LEP in the measurement of this Dipole Moment is discussed.

The tau weak-magnetic Dipole Moment
Nuclear Physics B, 1995Co-Authors: J Bernabeu, Michael M Tung, G. A. González-sprinberg, J. VidalAbstract:We calculate the prediction for the anomalous weak-magnetic form factor of the tau lepton at $q^2=M_Z^2$ within the Standard Model. With all particles on-shell, this is a electroweak gauge invariant quantity. Its value is $a_\tau^w (M_Z^2)= - \;(2.10 + 0.61\, i) \times 10^{-6}$. We show that the transverse and normal components of the single-tau polarization of tau pairs produced at $e^+e^-$ unpolarized collisions are sensitive to the real and absorptive parts of the anomalous weak-magnetic Dipole Moment of the tau. The sensitivity one can achieve at LEP in the measurement of this Dipole Moment is discussed.

ultracold rare earth magnetic atoms with an electric Dipole Moment
Physical Review Letters, 2018Co-Authors: Maxence Lepers, Goulven Quemener, Jean-françois Wyart, Hui Li, Olivier DulieuAbstract:: We propose a new method to produce an electric and magnetic dipolar gas of ultracold dysprosium atoms. The pair of nearly degenerate energy levels of opposite parity, at 17513.33 cm^{-1} with electronic angular Momentum J=10, and at 17514.50 cm^{-1} with J=9, can be mixed with an external electric field, thus inducing an electric Dipole Moment in the laboratory frame. For field amplitudes relevant to current-day experiments, i.e., an electric field of 5 kV/cm, we predict a large magnetic Dipole Moment up to 13 Bohr magnetons, and sizeable electric Dipole Moment up to 0.22 D. When a magnetic field is present, we show that the induced electric Dipole Moment is strongly dependent on the angle between the fields. The lifetime of the field-mixed levels is found in the millisecond range, thus allowing for suitable experimental detection and manipulation.
