Measurement of V-ud with 0(+) -> 0(+) nuclear beta decays

# abstract
Results from superallowed 0+0+ nuclear beta decays today provide the best value for Vud, with an uncertainty of 0.02%. Some 150 independent measurements of 13 separate superallowed transitions covering a wide range of parent nuclei from 10C to 74Rb constitute a very robust data set. Excellent consistency among the average results for all 13 transitions - an expected consequence of the conservation of vector current (CVC) - also confirms the validity of the small transition-dependent theoretical corrections that have been applied to account for isospin-symmetry breaking. With CVC consistency established, the value of the vector coupling constant, GV, has been extracted from the data and used to determine -Vud- = 0.97425 (22).  2013 AIP Publishing LLC.
