Limits on K L 0 → π 0 e + e − and K L 0 → e + e −

We report on a search for the flavor-changing neutral-current decays ${K}_{L}^{0}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{0}{e}^{+}{e}^{\ensuremath{-}}$ and ${K}_{L}^{0}\ensuremath{\rightarrow}{e}^{+}{e}^{\ensuremath{-}}$. Limits obtained for these processes are $B({K}_{L}^{0}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{0}{e}^{+}{e}^{\ensuremath{-}})l3.2\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}7}$ and $B({K}_{L}^{0}\ensuremath{\rightarrow}{e}^{+}{e}^{\ensuremath{-}})l1.2\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}9}$.
