25. CP violation and effective field theories

Peter Matthias Stoffer (PSI - Paul Scherrer Institut)

Oral Presentation

A dynamical explanation of the baryon asymmetry of the universe requires new sources of CP violation. Under the assumption that these are tied to heavy particles beyond the Standard Model, an effective field theory framework can be used to describe their effect on low-energy precision observables, such as electric dipole moments. I will review the challenges and recent progress to establish...

47. The nEDM Superfluid technique: prospects for 10^-28 e-cm

Oral Presentation

The path to an “ultimate” nEDM apparatus is small measurement cells for suppressing systematic effects to a manageable level while achieving a sufficiently high ultracold neutron (UCN) density to improve statistical reach. The nEDM Superfluid technique offers this by exploiting a fortuitous combination of the properties of superfluid $^4$He, polarized $^3$He, and polarized UCN, allowing high...
