We present the KLOE measurements on KS , KL , K ± semileptonic decays from which we find |Vus | = 0.2237(13). From the KLOE measurement of BR(K+→ μ+ í ) we obtain |Vus & Vud | = 0.2323(15). An overall fit gives |Vus | = 0.2249(10) and |Vud | = 0.97417(26), compatible with unitarity: 1- (V 2 ud + V 2 us +-4 . V 2 ub ) = (4 ± 7) × 10

Abstract
We present the KLOE measurements on KS , KL , K ± semileptonic decays from which we find |Vus | = 0.2237(13). From the KLOE measurement of BR(K+→ μ+ í ) we obtain |Vus & Vud | = 0.2323(15). An overall fit gives |Vus | = 0.2249(10) and |Vud | = 0.97417(26), compatible with unitarity: 1- (V 2 ud + V 2 us +-4 . V 2 ub ) = (4 ± 7) × 10File in questo prodotto:
