| dc.abstract.en | We present a new search for the $K_{S}\rightarrow 3\pi ^{0}$ decay performed with the KLOE detector operating at the DAΦNE $\phi$ -factory. The $K_{S}$ mesons were tagged via registration of $K_{L}$ mesons which crossed the drift chamber without decaying and interacted with the KLOE electromagnetic calorimeter. The $K_{S}\rightarrow 3\pi ^{0}$ decay was then searched requiring six prompt photons. To suppress background, originating from fake $K_{S}$ tags and $K_{S}\rightarrow 2\pi ^{0}$ decays with additional two spurious clusters, we have performed a discriminant analysis based on kinematical fit, testing of the signal and background hypotheses and exploiting of the differences in kinematics of the $K_{S}$ decays into $2\pi ^{0}$ and $3\pi ^{0}$. In a sample of about 1.7$\cdot 10^{9} \phi \rightarrow K_{S}K_{L}$ events we have found no candidates in data and simulated background samples. Normalizing to the number of $K_{S}\rightarrow 2\pi^{0}$ events in the same sample, we have set the upper limit on the $K_{S}\rightarrow 3\pi^{0}$ branching ratio BR $\left ( K_{S}\rightarrow 3\pi^{0} \right )< 2.6\cdot 10^{-8}$ at 90% C.L., five times lower than the previous limit. This upper limit can be translated into a limit on the modulus of the $\eta _{000}$ parameter amounting to $\left | \eta _{000} \right |< 0.0088$ at 90% C.L., improving by a factor two the latest direct measurement. | pl |
