Degree to which CVC is Established Through Beta Decay Alone

Precision studies of $0^{+} \rightarrow 0^{+}$ superallowed $β$ decays provide the necessary data to test stringently the CVC hypothesis. They will also provide a value for the weak vector coupling constant and the $V_{ud}$ quark mixing element of the Cabibbo-Kobayashi-Maskawa (CKM) matrix. The determination of this element is crucial for the test of the unitarity of the CKM matrix, and the search for physics beyond the Standard Model. This paper reviews the current status of $0^{+} \rightarrow 0^{+}$ $β$-decay data and their implications, as well as some relevant data from the $β$ decay of $^{19}$Ne and the neutron.

Recent Chalk River Experiments on Superallowed $0^{+} \to 0^{+}$ Beta Decays

Two experiments, (1) a measurement of the superallowed $0^{+} \rightarrow 0^{+}$ branching ratio in $^{10}$C, and (2) a measurement of (or limit on) non-analogue $0^{+} \rightarrow 0^{+}$ branches in $^{38m}$K, $^{46}$V, $^{50}$Mn and $^{54}$Co, are described. The implications these experiments have on the test of the conservation of the weak vector current (CVC) and the unitarity of the Cabibbo-Kobayashi-Maskawa matrix are surveyed.

Superallowed Fermi Beta Decay -- a Status Report

Data on superallowed Fermi beta decay in nuclei are compiled and electromagnetic corrections discussed. Recommended values for the weak vector coupling constant and the leading element of the Cabibbo-Kobayashi-Maskawa mixing matrix are given. Comments on neutron decay and limits extracted on extensions to the Standard Model are made.
