Abstract
New results from the NA48 experiment on kaon and hyperon decays relevant to |V_us| are reported here. For charged kaons we present measurements of BR(K+- -> pi0 e+- nu) and BR(K+- -> pi0 mu+- nu). On neutral kaon decays we report the measurements of BR(K_L -> pi+ pi-) and of K_L -> pi+- mu-+ nu form factors slopes. For hyperons we present results on the BR(Xi0 -> Sigma+ e- nu_e).
