Search for decays with semileptonic tagging at Belle

We present the results of a search for the rare decays $B\to h\nu\overline{\nu}$,where$h$standsfor$K^+,:K^0_{$\mathrm{S}$},:K^{\ast +},:K^{\ast 0},:\pi^+,:\pi^0,:\rho^+$and$\rho^{0}$. The results are obtained with $772\times {10}^6$ $B\bar{B}$ pairs collected with the Belle detector at the KEKB $e^{+}{e}^{-}$ collider. We reconstruct one $B$ meson in a semileptonic decay and require a single $h$ meson but nothing else on the signal side. We observe no significant signal and set upper limits on the branching fractions. The limits set on the $B\to K^0_{$\mathrm{S}$}\nu\overline{\nu}$,$B^0\to K^{*0}\nu\overline{\nu}$,$B\to \pi^+\nu\overline{\nu}$,$B^0\to\pi^0\nu\overline{\nu}$,$B^+\to\rho^+\nu\overline{\nu}$,and$B^0\to\rho^0\nu\overline{\nu}$ channels are the world’s most stringent.
