Superallowed Nuclear Beta Decay: A Window on the Weak Interaction
- Cyclotron Institute, Texas A and M University, College Station, TX, 77843 (United States)
Measurements on superallowed 0{sup +}{yields}0{sup +} nuclear beta transitions currently provide the most demanding test of the Conserved Vector Current (CVC) hypothesis and the most precise value for the up-down element, V{sub ud}, of the Cabibbo-Kobayashi-Maskawa (CKM) matrix. Both are sensitive probes for physics beyond the Standard Model. Analysis of the experimental results depends on small radiative and isospin-symmetry-breaking corrections whose uncertainties now dominate those from experiment. Recent experiments have been focusing on tests of these corrections with a view to reducing their uncertainties. An overview is presented together with a description of measurements at Texas A and M on the superallowed decay of {sup 34}Ar.
