Abstract :
A re-analysis of Jπ=0+ → 0+ super-allowed Fermi transitions, following Wilkinson (Nucl. Instr. and Meth. A 488 (2002) 654), using further input and a more-detailed procedure yields |Vud|2=0.9500±0.0009; |Vud|2+|Vus|2+|Vub|2=0.9982±0.0015 or |Vud|2+|Vus|2+|Vub|2=0.9993±0.0013 with the operational vector coupling constant G∗V/(ℏc)3=(1.15050±0.00027)×10−5 GeV−2.
