Description
The authors study the KΒ decays and show that a large isospin breaking effect is present in experimental data of Kμ3. From the Kμ3 and Ke3 rates, they determine the following weighted averages values: |f+K0→n-(0)Vusμ3| = 0.2086 ± 0.0012 and |f+K+→π0(O)Vus| = 0.2169 ± 0.00016 with f+K→π(0) being the vector charge of the weak transition K → π
