Abstract

We present the first experimental limits on high-q2 contributions to charmless semileptonic B decays of the form expected from the weak annihilation (WA) decay mechanism. Such contributions could bias determinations of |Vub| from inclusive measurements of B→Xulν. Using a wide range of models based on available theoretical input we set a limit of ΓWA/Γb→u<7.4% (90% confidence level) on the WA fraction, and assess the impact on previous inclusive determinations of |Vub|.
