  1. 94. A large Muon Electric Dipole Moment from Flavor?
    Mr Timo Rüppell (Helsinki Institute of Physics)
    14/10/2010, 14:30
    Searches for symmetry violations
    Oral
    We study the prospects and opportunities of a large muon electric dipole moment (EDM) of the order 10^-24 ecm -- 10^-22 ecm. We investigate how natural such a value is within the general minimal supersymmetric extension of the Standard Model with CP violation from lepton flavor violation in view of the experimental constraints. In models with hybrid gauge-gravity mediated supersymmetry...

  2. 73. The New g-2 and Muon EDM experiment at Fermilab
    Prof. David Hertzog (University of Washington)

    Precision experiments with pions and muons
    Oral
    The Brookhaven E821 experiment measured the muon's anomalous magnetic moment to a precision of 0.54 ppm. At this time, the standard model prediction is known to similar precision. When experiment and theory are compared, the difference exceeds 3 standard deviations in significance. What is this telling us? I will review the current status, the more popular interpretations, and most...

  3. 22. Search for EDMs Using Storage Rings

    Searches for symmetry violations
    Oral
    An electric dipole moment (EDM) aligned with the spin of a fundamental particle violates both parity conservation and time reversal invariance, or, via the presumed CPT conservation, CP invariance. Standard Model predictions are much below current or anticipated experimental sensitivity levels; an observation within the next generation of searches will represent a new signature of CP...

  4. 58. Search for a neutron EDM at SNS
    Dr Takeyasu Ito (Los Alamos National Laboratory)

    Searches for permanent electric dipole moments
    Oral
    The nEDM Collaboration is developing an experiment to run at the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory to search for the neutron electric dipole moment (EDM) with a sensitivity of <10^{-27} e cm based on the scheme proposed by Golub and Lamoreaux. The collaboration has been working on various R&D experiments to establish the technical feasibility of the experiment...

  5. 14. The search for the neutron electric dipole moment at the Paul Scherrer Institut
    Dr Stephanie Roccia (KUL Leuven)
    14/10/2010, 16:00
    Searches for permanent electric dipole moments
    Oral
    The measurement of the neutron electric dipole moment (nEDM) constrains the contribution of CP-violating terms within both the standard model and its extensions. The limit, or even the observation of an EDM would also add profoundly to the understanding of the baryon-asymmetry of the universe. The experiment set up at the Paul Scherrer Institut (PSI), Switzerland, uses ultra-cold neutrons...
