Query: Measurement of the branching ratio for the decay $K^\pm \to \pi^\pm
  \pi^0 \pi^0$ with the KLOE detector   A new measurement of the absolute branching ratio BR($K^\pm \to \pi^\pm \pi^0
\pi^0$) with the KLOE detector at the DA$\Phi$NE $e^+e^-$ collider is
presented, based on a sample of $\sim 3.3\times 10^7$ charged kaons tagged
events, produced in the reaction $e^+e^-\to\phi\to K^+K^-$.The value BR($K^\pm
\to \pi^\pm \pi^0 \pi^0$) $= (1.781\pm 0.013_{stat}\pm 0.016_{syst})%$ has been
obtained.
