Fundamental physics and precision experiments with muons, pions, neutrons, antiprotons, and other particles
Oral
In this talk, we present an overview of the science program at the Los Alamos spallation-driven solid-deuterium ultra-cold neutron (UCN) source, describe the performance of the source, and give the status of the source upgrade now underway. Experiments in operation or development include the UCNTau neutron lifetime experiment, UCNB/Nab detector development for measurement of neutron beta decay...

Searches for permanent electric dipole moments
Oral
Searches for the permanent electric dipole moments of atoms, nucleons, and nuclei provide one of the most powerful probes of CP-violation beyond the Standard Model. I survey the opportunities for discovering BSM CP-violation with the present and next generation EDM searches; discuss the complementary of searches using different systems; and highlight the implications of these searches for...

Searches for permanent electric dipole moments
Oral
A permanent non-zero electric dipole moment (nEDM) violates CP-symmetry. Beyond Standard Model theories predict nEDMs very close to the current upper limit of 3x10^(-26)ecm.
Those predictions result from CP-violating processes, which in turn can be related to the matter-antimatter asymmetry observed in our universe. Thus the search for an nEDM contributes to understanding the Baryon...

Searches for permanent electric dipole moments
Oral
The behavior of a spin undergoing Larmor precession in the presence of fluctuating fields is of interest to a variety of precision measurement experiments. The fluctuating fields cause frequency shifts and relaxation which according to Redfield theory are related to their power spectrum. Recently it was shown that scattering with energy exchange from an ensemble of scatterers in thermal...

Searches for permanent electric dipole moments
Oral
For more than fifty years physicists have tried to measure the electric dipole moment of the
neutron (nEDM). The limit on the nEDM has become smaller and smaller, but at present
its value remains consistent with zero. However, the Standard Model of particle physics
predicts a small non-zero value, as do the various extensions of the Standard Model. The
predictions span several orders of...
