Issue Date: | Nov-2009 | Publisher: | Società Italiana di Fisica | Source: | 1 | 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+ν) we obtain |Vus/Vud| = 0.2323(15). An overall fit gives |Vus| = 0.2249(10) and |Vud| = 0.97417(26), compatible with unitarity: 1 − (V2ud + V2us +V2ub) = (4 ± 7) × 10−4. | URI: | http://hdl.handle.net/2307/324 | DOI: | 10.1393/ncc/i2009-10457-9 |
