ON THE DETERMINATION OF A(1) AND A(2) FROM HADRONIC 2 BODY-B DECAYS

From Class I decays:B0 --> pi+(rho+)+D-(D-), we determine a1, and fro m Class III decays: B+ --> pi+(rho+)+D0BAR(D0BAR), we determine an al lowed domain in the (a1,a2) Plane. We find that within one standard de viation errors, the allowed band of a1 from Class I decays is at least three standard deviations removed from the allowed domain (a1,a2) fro m Class III decays. If we expand the experimental errors to two standa rd deviations we do find a small intersection between the a1 band and the allowed (a1,a2) domain. The results usually quoted in the literatu re lie in this intersection. We suggest: (1) an independent measuremen t of the branching ratio for the Class III decay, B+ --> rho+D0BAR, (2 ) a high-statistics measurement of the branching ratio of the Class I decay, B --> DBAR(DBAR) + D(s)(D(s*)) in both charged states, and (3) a measurement of the longitudinal polarization fraction in the Class III decay B+ --> rho+D0BAR to shed more light on the questions involv ed.
