Search for the Electric Dipole Moment of the τ Lepton
We have searched for a CP violation signature arising from an electric dipole moment (dτ ) of the τ lepton in the e e → ττ reaction. Using an optimal observable method and 29.5 fb of data collected with the Belle detector at the KEKB collider at √ s = 10.58 GeV, we find Re(dτ ) = (1.15 ± 1.70) × 10e cm and Im(dτ ) = (−0.83 ± 0.86) × 10e cm and set the 95% confidence level limits −2.2 < Re(dτ ) ...
متن کاملτ electric dipole moment with polarized beams
High luminosity Super B/Flavor factories, near and on top of the Υ resonances, allow for a detailed investigation of CP-violation in τ physics. In particular, bounds on the τ 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 ...
متن کاملElectric Dipole Moment of Magnetic Monopole
The electric dipole moment of a magnetic monopole with spin is studied in the N = 2 supersymmetric gauge theory. Dipole moments of electric charge distributions, as well as dipole moments due to magnetic currents, are calculated. The contribution of the charge distribution of the fermion to the gyroelectric ratio is expressed in terms of ζ(3).
متن کاملThe Muon Electric Dipole Moment
The electric dipole moment of the muon (dμ) is evaluated in a two Higgs doublet model with a softly broken discrete symmetry. For tan β ≡ |v2|/|v1| ∼ 1, contributions from two loop diagrams involving the t quark and the W boson dominate; while for tan β ∼ > 10, contributions from two loop diagrams involving the b quark and the τ lepton are dominant. For 8 ∼ > tan β ∼ > 4, significant cancellati...
متن کاملLepton Anomalous Magnetic Moment
This article reviews and updates the Standard Model prediction of the τ lepton g−2. Updated QED and electroweak contributions are presented, together with new values of the leading-order hadronic term, based on the recent low energy ee data from BaBar, CMD-2, KLOE and SND, and of the hadronic light-by-light contribution. The total prediction is confronted to the available experimental bounds on...
