X0(2900) and its spin partners productions in the B+ decay processes.

In the present work, we investigate the productions of X 0 (2900) and its spin partners in the B + decay processes, where X 0 (2900) is regarded as a D ¯ ∗ K ∗ molecular state. We infer that the initial B + meson and the final D + X 0 (2900) are connected through the D s 1 ′ + (2460) D ¯ ∗ 0 mesons by exchanging a K ∗ 0 meson. The contributions of such a meson loop to the process B + → D + X 0 (2900) are evaluated and our estimations indicate that the measured branching fraction of B + → D + X 0 (2900) could be well reproduced in a reasonable range of model parameters, indicating that X 0 (2900) could be interpreted as a D ¯ ∗ K ∗ molecular state. In addition, the production processes B + → D + X ~ 1 , 2 , B + → D ∗ + X 0 (2900) , and B + → D ∗ + X ~ 1 , 2 are investigated, and we find that the fit fraction of X ~ 1 in the process B + → D ∗ + D ∗ - K + is about 6%, which should be accessible by the LHCb and Belle II Collaborations.
