Measurement of the KS → πeν branching fraction with the KLOE experiment
Abstract The ratio R $$ \mathcal{R} $$ = Γ(K S → πeν)/Γ(K S → π + π − ) has been measured with a sample of 300 million K S mesons produced in ϕ → K L K S decays recorded by the KLOE experiment at the DAΦNE e + e − collider. K S → πeν events are selected by a boosted decision tree built with kinemati...
