Possible hadronic molecules composed of the doubly charmed baryon and nucleon

TL;DR

This paper explores the potential existence of deuteron-like bound states formed by doubly charmed baryons and nucleons using a one-boson-exchange model, predicting several loosely bound molecular states that could be experimentally observed.

Contribution

It systematically investigates possible hadronic molecules involving $ ext{Xi}_{cc}$ baryons and nucleons, including tensor force effects, within the one-boson-exchange framework, identifying potential bound states.

Findings

Several candidate bound states below $ ext{Lambda}_c ext{Lambda}_c$ threshold.

Loosely bound states with $ ext{Xi}_{cc}N$ and $ ext{Xi}_{cc}ar{N}$ configurations identified.

Potential experimental detection at Belle II and LHC.

Abstract

We perform a systematical investigation of the possible deuteron-like bound states with configuration $\Xi_{cc}N (\bar{N})$, where $N(\bar{N})$ denotes the nucleon (anti-nucleon), in the framework of the one-boson-exchange-potential model. In the spin-triplet sector we take into account both the ${}^3S_1$ and ${}^3D_1$ channels due to non-vanishing tensor force. There exist several candidates of the loosely bound molecular states for the $\Xi_{cc}N$ and $\Xi_{cc}\bar{N}$ systems, which lie below the threshold of $\Lambda_c\Lambda_c$ or $\Lambda_c{\bar\Lambda}_c$. We also investigate the possible loosely bound states with configurations $\Lambda_cN(\bar{N})$ and $\Sigma_cN(\bar{N})$. These molecular candidates may be searched for at Belle II and LHC in the near future.
