The branching fraction for the decay $K_S \to πe ν$ has been measured with a sample of 300 million $K_S$ mesons produced in $ϕ\to K_L K_S$ decays recorded by KLOE experiment at DA$Φ$NE $e^+e^-$ collider. Signal are selected boosted decision tree built kinematic variables and time-of-flight measurements. Data control samples $K_L used to evaluate signal selection efficiencies. A fit reconstructed electron mass distribution finds 49647$\pm$316 events. Normalising π^+π^-$ events result is...
