$X(4630)$ and $Y(4626)$ production in the B⁺ and Bₛ⁰ decays

In the present work, we investigate the production of $X(4630)$ and $Y(4626)$ in B⁺ and Bₛ⁰ decays, where $X(4630)$ and $Y(4626)$ are considered as the $C-$ parity pigeon pair in the Dₛ⁺ Dₛ₁(2536)⁻ molecular frame. The branching fractions of B⁺ → K⁺ X(4630)/Y(4626) and Bₛ⁰ → η X(4630)/Y(4626) have been evaluated using an effective Lagrangian approach, which are of the order of 10⁻⁵ and the ratios of these branching fractions are almost independent on the model parameter. Based on the present estimations, we propose to search $Y(4626)$ in the process B⁺ → K⁺ J/ψ η⁽⁾, which should be accessible by the LHCb and Belle II Collaborations.
