Search for B − → μ − ν ¯ μ Decays at the Belle Experiment

We report the results of a search for the rare, purely leptonic decay B−→μ−ν¯μ performed with a 711  fb−1 data sample that contains 772×106  BB¯ pairs, collected near the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e− collider. The signal events are selected based on the...
