Abstract
We have measured the absolute branching ratio BR(K+/- --> pi(+/-)pi(0)pi(0)) with the KLOE detector at the DAPhiNE e(+)e(-) collider. We collected similar to 3.3 x 10(7) tagged charged kaons, from the reaction e(+)e(-) --> phi --> K+K-. We find BR(K+/- --> pi(+/-)pi(0)pi(0)) = (1.763 +/- 0.013(stat) +/- 0.022(syst)) x 10(-2).
