Understanding $B^-\rightarrow X(3823)K^-$ via rescattering mechanism and predicting $B^-\to ��_{c2} (^1D_2)/��_3(^3D_3)K^-$
説明
We study the observed $B^-\rightarrow X(3823)K^-$ decay via rescattering mechanism and show that this branching ratio is well reproduced by this mechanism. We further extend this theoretical framework to investigate the decays of $B^-\to��_{c2} (^1D_2)/��_3(^3D_3)K^-$, where the $��_{c2} (^1D_2)$ and the $��_3(^3D_3)$ are $D$-wave charmonium partners of the $X(3823)$. Our results show that the branching ratios, $B^-\to ��_{c2}(^1D_2) K^-$ and $B^-\to ��_3(^3D_3) K^-$, are of the order of $10^{-5}$, which can be accessible at LHCb, Belle and forthcoming BelleII.
