摘要: In this talk I’ll start with introducing the general approach of effective field theory. Then I recall briefly the history of research on nuclear beta decays. I’ll spend most of time describing the effective field theories for beta decays at both the quark and nucleon levels and their connection. I’ll review the current experimental status on the decays and their comparison with the standard model predictions and their constraints on high energy new physics. The potential neutron lifetime anomaly is also briefly discussed together with an example of possible new physics interpretation. I summarize with some comments on perspectives in this field.
