Abstract
Two-body vector-vector decal modes of B mesons are investigated in the quar k diagram scheme. Several relations among the decay amplitudes are obtained . Relations among the branching ratios are also obtained. which are found t o be consistent with the available data. Smearing effects arising due to th e large width of the p resonance are also investigated in this scheme, and have been found to lower the branching ratios in the right direction to the extent of about 20-25%.
