New results on $K_{L}$ and $K_{S}$ rare decays by NA48
New measurements of the branching ratios $K_{L} \to e^{+}e^{-} e^{+}e^{-}$ and $K_{L} \to \pi^{0}\gamma\gamma$ are presented. The use of a target placed nearby the beginning of the decay region allows sensitive $K_{S}$ rare decay searches: we report a new measurement of BR$(K_{S} \to \gamma\gamma)$...

| description | New measurements of the branching ratios $K_{L} \to e^{+}e^{-} e^{+}e^{-}$ and $K_{L} \to \pi^{0}\gamma\gamma$ are presented. The use of a target placed nearby the beginning of the decay region allows sensitive $K_{S}$ rare decay searches: we report a new measurement of BR$(K_{S} \to \gamma\gamma)$ and a new upper limit for the decay $K_{S} \to \pi^{0}e^{+}e^{-}$. |
