N2 - We study the productions of p-wave mesons K0*(1430), K1(1270), and K1(1400) in B decays. By the generalized factorization approach, we find that the branching ratios of B→K0*(1430) are similar to those of B→K while the branching ratios of B→K1(1270) and B→K1(1400) are O(10-5) and O(10-6), respectively. In terms of the observation of B→K1(1270)γ by BELLE, we can remove the sign ambiguity in the mixing angle for physical states K1(1270) and K1(1400). In addition, we analyze annihilation contributions in the decays B→K1 and we conclude that they could be neglected.
