Abstract: (APS)

We discuss the possibility of measuring Vub via nonleptonic decays of B mesons to exclusive two-meson final states by choosing modes that are theoretically "clean." These clean final states are chosen by requiring that no qq¯ of the same flavor should occur in them. The above requirement automatically leads to decays that proceed only via the spectator graphs in the decays of b, c, and s flavored mesons. These modes may offer a good handle on Vub, at a level comparable to that given by the exclusive semileptonic modes.
