Radiative Beta Decay for Studies of CP Violation

The slight difference in the interactions of matter and anti-matter connotes CP violation. CP violation has been studied extensively in weak decays, and thus far, save for some tantalizing hints, all is consistent with the Standard Model. However, our inability to explain the baryon excess we observe in the universe suggests that additional sources of CP violation must exist, though experiment tells us that these sources appear to be associated with energy scales currently beyond our reach. In this context improved limits on processes which are highly forbidden in the Standard Model, such as the permanent electric dipole moments of ground-state particles or certain, rare decay observables, bound new sources of CP violation. In this talk I discuss the possibility of using a triple momentum correlation in the radiative beta-decay of neutrons and nuclei as a new probe of CP-violating effects.
