Parity- and time-reversal-violating moments of light nuclei

Abstract

I present the calculation of parity-and time-reversal-violating moments of the nucleon and light nuclei, originating from the QCDθ term and effective dimension-six operators. By applying chiral effective field theory these calculations are performed in a unified framework. I argue that measurements of a few light-nuclear electric dipole moments would shed light on the mechanism of parity and time-reversal violation.
