Proposal for a Precision Measurement of |Vub|
arXiv:hep-ph/0403223 · doi:10.1103/PhysRevLett.93.221801
Abstract
A new method for a precision measurement of the CKM matrix element |Vub| is discussed, which combines good theoretical control with high efficiency and a powerful discrimination against charm background. The resulting combined theoretical uncertainty on |Vub| is estimated to be 10%.
