“Probing the Standard Model and Beyond with Electric Dipole Moments”

 

 

 

Abstract: 

A Electric Dipole Moment or EDM is a separation of charge along the angular momentum of a particle or system that arises due to  parity and time-reversal odd elementary-particle interactions. Assuming CPT invariance, an EDM requires CP-violation. Experiments designed to measure EDMs, first with neutrons, started six decades ago, and though no EDM had been detected, the motivations are stronger, and the number of experiments and systems are increasing. Among the strongest motivations for EDM searches are the connection to baryogenesis, which requires beyond Standard-Model CP violation, and the sensitivity to new physics at the TeV scale. It's an exciting time for EDM experiments with a number of neutron, atomic and molecular EDM experiments under development, and new approaches including rare isotopes and storage-ring EDM experiments. In this talk I will discuss motivations and provide an overview of experimental prospects with emphasis on upcoming innovations and anticipated advances.
