We have measured the absolute branching ratio BR(K±→π±π0π0) with the KLOE detector at the DAΦNE e+e− collider. We collected ∼3.3×107 tagged charged kaons, from the reaction e+e−→ϕ→K+K− . We find BR(K±→π±π0π0)=(1.763±0.013stat±0.022syst)×10−2 .

Abstract
We have measured the absolute branching ratio BR(K±→π±π0π0) with the KLOE detector at the DAΦNE e+e− collider. We collected ∼3.3×107 tagged charged kaons, from the reaction e+e−→ϕ→K+K− . We find BR(K±→π±π0π0)=(1.763±0.013stat±0.022syst)×10−2 .File in questo prodotto:
