标题： Strong decays of $P-$wave doubly charmed and bottom baryons

摘要： 在本工作中，我们在组成子夸克模型中研究了双重魅夸克和底夸克重子的$P-$波激发态的强衰变。 我们的结果表明，一些$\lambda-$模式$\Xi_{cc/bb}(1P)$和$\Omega_{cc/bb}(1P)$状态相对较窄，很可能在未来实验中被发现。 由于初始态和末态波函数之间的正交性，低能的$\rho-$模式状态的轻介子发射高度被抑制。 此外，双重魅夸克和底夸克重子的强衰变行为很好地保持了重夸克超风味对称性，其中小的破坏来自于有限的重夸克质量以及不同的相空间。 我们希望目前对于未被发现的双重魅夸克和底夸克重子的理论结果能为未来实验提供有用的信息，并帮助我们更好地理解重夸克对称性。 显示英文摘要

摘要： In this work, we investigate the strong decays for $P-$wave excited states of doubly charmed and bottom baryons in the constituent quark model. Our results indicate that some $\lambda-$mode $\Xi_{cc/bb}(1P)$ and $\Omega_{cc/bb}(1P)$ states are relatively narrow, which are very likely to be discovered by future experiments. The light meson emissions for the low-lying $\rho-$mode states are highly suppressed due to the orthogonality of wave functions between initial and final states. Moreover, the strong decay behaviors for doubly charmed and bottom baryons preserve the heavy superflavor symmetry well, where the small violation originates from the finite heavy quark masses and different phase spaces. We hope that present theoretical results for undiscovered doubly charmed and bottom baryons can provide helpful information for future experiments and help us to better understand the heavy quark symmetry.
