Abstract

We present the results of a search for the rare decays Bhνν¯, where h stands for K+,KS0,K*+,K*0,π+,π0,ρ+ and ρ0. The results are obtained with 772×106BB¯ 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 B0KS0νν¯, B0K*0νν¯, B+π+νν¯, B0π0νν¯, B+ρ+νν¯, and B0ρ0νν¯ channels are the world’s most stringent.
