  1. 74. ACME Measurements of the Electron EDM
    Gerald Gabrielse (Harvard University)
    12/06/2018, 10:00
    Talk

    The ACME Collaboration has made the most sensitive measurement of the electric dipole moment of the electron. This moment is of great interest because the Standard Model predicts it should be too small to measure, supersymmetric and other model predict it should be small but measurable, and not nearly enough CP violation has been discovered to account for how a universe could survive the big...

  3. 4. Improved Measurement of the Permanent Electric Dipole Moment of $^{199}$Hg
    Dr Brent Graner (University of Washington)
    12/06/2018, 11:20
    Talk

    This talk will cover the latest results on the permanent electric dipole moment (EDM) of neutral $^{199}$Hg atoms. The EDM is manifested as a small perturbation to the Larmor precession frequency due to the interaction energy of the electric dipole with a static electric field. The atoms are prepared in four separate glass vapor cells using optical pumping with resonant 254 nm laser light and...

  4. 55. Recent Progress of the JEDI Collaboration
    Martin Gaisser (RWTH Aachen University)
    12/06/2018, 11:40
    Talk

    Electric Dipole Moments (EDMs) of elementary particles are important candidates
    for CP violation and hence possible sources for the observed matter-antimatter
    asymmetry in the universe. The Jülich Electric Dipole Moment Investigation
    (JEDI) collaboration is searching for EDMs of light nuclei. Ideally this would
    be done in a designated storage ring using the frozen spin concept. Such a ring...

  5. 46. Searches for the electric dipole moment of the neutron
    Dr Philipp Schmidt-Wellenburg
    12/06/2018, 12:00
    Talk

    Searches for electric dipole moments (EDM) of fundamental particles are considered one of the most sensitive approaches to physics beyond the Standard Model of particle physics (SM). A non-SM mechanism violating the combined symmetry of charge conjugation and parity inversion (CP-violation) could help to explain the observed baryon asymmetry of the Universe while manifesting itself as electric...

  6. 78. Electric Dipole Moments of the Nucleon and Light Nuclei in Chiral Effective Field Theory
    Dr Andreas Wirzba (Forschungszentrum Jülich GmbH)
    15/06/2018, 09:00
    Talk

    A nonzero electric dipole moment (EDM) of the neutron, proton, deuteron
    or helion, in fact, of any finite system necessarily involves the breaking of a symmetry,
    either by the presence of external fields (i.e., electric fields leading to the case of
    induced EDMs) or
    explicitly by the breaking of the discrete parity and time-reflection symmetries in the
    case of permanent EDMs.
    Recent...
