TL;DR

This paper predicts possible charm-strange molecular states involving nucleons and charmed baryons using a one-boson-exchange model, considering complex interactions and channel couplings, to guide future experimental searches.

Contribution

It introduces a comprehensive theoretical framework for predicting novel charm-strange molecular states, including effects of S-D wave mixing and coupled channels.

Findings

Prediction of several charm-strange deuteronlike $ ext{Xi}_c^{(',*)}N$ hexaquarks.

Identification of $ ext{Xi}_c^{ ext{'}}N$ molecules with specific quantum numbers.

Proposal of $ ext{Xi}_c^*N$ molecules and coupled-channel states as potential bound states.

Abstract

In the framework of a one-boson-exchange model, we carry out a comprehensive investigation of the $\Xi_cN/\Lambda_c\Sigma/\Xi_c^{\prime}N/\Sigma_c\Lambda/\Xi_c^*N/\Sigma_c^*\Lambda/\Sigma_c\Sigma/\Sigma_c^*\Sigma$ interactions. We consider the $S$-$D$-wave mixing effects and the coupled-channel effects to derive the relevant effective potentials. Our results can predict several possible charm-strange deuteronlike $\Xi_c^{(',*)}N$ hexaquarks, the $\Xi_c^{\prime}N$ molecules with $I(I^P)=0(0^+)$, $0(1^+)$, $1(1^+)$, the $\Xi_c^*N$ molecules with $0(1^+)$, $0(2^+)$, $1(2^+)$, and the coupled $\Xi_cN/\Xi_c^{\prime}N/\Xi_c^*N/\Sigma_c\Sigma/\Sigma_c^*\Sigma$ molecule with $0(1^+)$. We expect the experiments to search for our predictions of the $\Xi_c^{(\prime,*)}N$ bound states.
