Productions of $K^*_0(1430)$ and $K_{1}$ in B decays

Abstract

We study the productions of p-wave mesons $K^*_{0}(1430)$, $K_{1}(1270)$ and $K_{1}(1400)$ in B decays. By the generalized factorization approach, we find that the branching ratios of $B\to K^*_{0}(1430) ϕ$ are similar to those of $B\to K ϕ$ while the branching ratios of $B\to K_{1}(1270) ϕ$ and $B\to K_{1}(1400) ϕ$ are $O(10^{-5})$ and $O(10^{-6})$, respectively. In terms of the observation of $B\to K_{1}(1270) γ$ by BELLE, we can remove the sign ambiguity in the mixing angle for physical states $K_1(1270)$ and $K_{1}(1400)$. In addition, we analyze annihilation contributions in the decays $B\to K_1 ϕ$ and we conclude that they could be neglected.
