e???-Decay and the electric dipole moment: Searches for time-reversal violation in radioactive nuclei and atoms

摘要

One of the greatest successes of the Standard Model of particle physics is the explanation of time-reversal violation (TRV) in heavy mesons. It also implies that TRV is immeasurably small in normal nuclear matter. However, unifying models beyond the Standard Model predict TRV to be within reach of measurement in nuclei and atoms, thus opening an important window to search for new physics. We will discuss two complementary experiments sensitive to TRV: Correlations in the e???-decay of 21Na and the search for an electric dipole moment (EDM) in radium.
