摘要:

我们研究了所观察到的$B^-\rightarrow X(3823)K^-$衰变通过再散射机制,并表明,这种分支比是很好地再现了这种机制。我们进一步扩展这个理论框架来研究$B^-\toη_{c2} (^1D_2)/ψ_3(^3D_3)K^-$的衰变,其中$η_{c2} (^1D_2)$和$ψ_3(^3D_3)$是$X(3823)$的$D$波粲偶素伙伴.我们的结果表明,分支比$B^-\to η_{c2}(^1D_2) K^-$和$B^-\to ψ_3(^3D_3) K^-$的数量级为$10^{-5}$,可以在LHCb、Belle和即将推出的Belle II上访问。

英文摘要:

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 $B^-\toη_{c2} (^1D_2)/ψ_3(^3D_3)K^-$, where the $η_{c2} (^1D_2)$ and the $ψ_3(^3D_3)$ are $D$-wave charmonium partners of the $X(3823)$. Our results show that the branching ratios, $B^-\to η_{c2}(^1D_2) K^-$ and $B^-\to ψ_3(^3D_3) K^-$, are of the order of $10^{-5}$, which can be accessible at LHCb, Belle and forthcoming BelleII.
