We have measured the fully inclusive K+ -> mu+nu(gamma) absolute branching ratio with KLOE experiment at DAFNE, Frascati Phi-factory. From some 865,283 decays obtained from a sample of about 5.2x10^8 Phi-meson decays, we find BR(K+ mu+ nu (gamma)) = 0.6366 +-0.0009(stat.) +-0.0015(syst.), corresponding to an overall fractional error 0.27%. Using recent lattice results on decay constants pseudoscalar mesons one can obtain estimate for CKM mixing matrix element |Vus|=0.2223+-0.0026.
We present a measurement of the KL lifetime using KLOE detector. From sample 4 x 10^8 KS pairs following reaction e+ e- -> phi we select 15 10^6 p0 decays tagged by pi+ pi- events. fit proper time distribution find tau_L = (50.92 +- 0.17{stat} 0.25{syst})$ ns. This is most precise performed to date.
