Superallowed nuclear beta decay: A window on the weak interaction Conference Paper uri icon

abstract

  • Measurements on superallowed 0+ 0+ 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, Vnd, 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&M on the superallowed decay of 34Ar. 2008 American Institute of Physics.
