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...

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...

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...

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...

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...
