| dc.description.abstract | The new proposals for high luminosity B/Flavor factories, near and on top of the Y resonances, allow for a detailed investigation of CP-violation in the pi-pair production. In particular, bounds on the tau electric dipole moment can be obtained of genuine CP-odd observables related to the pi-pair production. We perform an independent analysis from low energy (10 GeV) data by means of linear spin observables. We show that for a longitudinally polarized electron beam a CP-odd asymmetry, associated to the normal polarization term, can be measured at these low energy facilities both at resonant and non-resonant energies. In this way stringent and independent bounds to the tau electric dipole moment, which are orders of magnitude below other high or low energy previous bounds, can be obtained. | |
