] beta decays [4], CKM unitarity (assumes conserved vector current, CKM unitarity, and values of |[V.
The decay is interpreted according to the universal V-A theory of weak interactions [2] with a conserved vector current derived from an approximate global symmetry of the QCD Lagrangian [3].
Precision measurements of these parameters can test the unitarity of the Cabibbo-Kobayashi-Maskawa (CKM) matrix, provide limits on weak scalar and tensor currents, right-handed currents, conserved vector current (CVC) violation and second-class currents, and other possible new physics beyond the Standard Model of particle physics.
