论文摘要
在这项工作中，我们系统地研究了具有魅力数量$ c $ = 1和strangeness $ s $ = $ s $ = $ \ pm $ $ 1的Dibaryons，从迷人的Baryon和一个奇怪的Baryon $λ_cλ$，$λ_cλ$，$λ_cς^{（*） $σ^{（*）} _cς^{（*）} $，以及魅力baryon和antistrange baryon $λ_c\barλ$，$λ_c\ barvid $σ^{（*）} _ c \barς^{（*）} $。在有效的Lagrangians的帮助下，$ SU（3）$，重型夸克和手性对称性，所考虑的相互作用的潜力是由轻型介子交易所构建的。为了搜索可能的分子，求解具有相互作用电势核的准贝尔 - 钙板方程，以从散射幅度找到极点。结果表明，景点在Charmed-Strange系统中广泛存在，$ C $ = 1和$ S $ = $ - 1 $。 $ s $波绑定的状态可以从大多数渠道产生。从魅力的抗散布互动中也很少能产生绑定的状态。在当前的工作中考虑了夫妇通道效应，以讨论分子状态与所考虑的通道的耦合。建议对这些Charmed-Strange Dibaryons进行更多的实验研究。
In this work, we systematically investigate the dibaryons with charm number $C$=1 and strangeness number $S$=$\pm$ 1 from the interactions of a charmed baryon and a strange baryon $Λ_cΛ$, $Λ_cΣ^{(*)}$, $Σ_c^{(*)}Λ$, and $Σ^{(*)}_cΣ^{(*)}$, and corresponding interactions of a charmed baryon and an antistrange baryon $Λ_c\barΛ$, $Λ_c\barΣ^{(*)}$, $Σ^{(*)}_c\barΛ$, and $Σ^{(*)}_c\barΣ^{(*)}$. With the help of the effective Lagrangians with $SU(3)$, heavy quark, and chiral symmetries, the potentials of the interactions considered are constructed by light meson exchanges. To search for the possible molecules, the quasipotential Bethe-Salpeter equation with the interaction potential kernel is solved to find poles from scattering amplitude. The results suggest that attractions widely exist in charmed-strange system with $C$=1 and $S$=$-1$. The $S$-wave bound states can be produced from most of the channels. Few bound states are also produced from the charmed-antistrange interactions. Couple-channel effect are considered in the current work to discuss the couplings of the molecular states to the channels considered. More experimental research for these charmed-strange dibaryons are suggested.
