Abstract
We present a search for the decays B+âμ+νμ and B+âe+νe in a 253 fbâ1 data sample collected at the Ï(4S) resonance with the Belle detector at the KEKB asymmetric-energy B factory. We find no significant evidence for a signal and set 90% confidence level upper limits of B(B+âμ+νμ)<1.7Ã10â6 and B(B+âe+νe)<9.8Ã10â7.
