title: Proposal for a precision measurement of |Vub|.
abstract: A new method for a precision measurement of the Cabibbo-Kobayashi-Maskawa matrix element |V(ub)| is discussed, which combines good theoretical control with high efficiency and a powerful discrimination against charm background. The resulting combined theoretical uncertainty on |V(ub)| is estimated to be 10%.
