Charmed baryon in a string model

TL;DR

This paper models charmed baryons using a string approach, predicting energy levels and diquark masses, and compares these with experimental data to enhance understanding of their structure.

Contribution

It introduces a string model for charmed baryons, providing energy predictions for excitations and diquark mass calculations consistent with observed data.

Findings

Predicted energy levels for first and second orbital excitations.

Diquark masses satisfy spin-spin splitting relations.

Some correspondences with experimental data.

Abstract

Charm spectroscopy has studied under a string model. Charmed baryons are composed of diquark and charm quark which are connected by a constant tension. In a diquark picture, the quantum numbers $J^P$ of confirmed baryons are well assigned. We give energy predictions for the first and second orbital excitations. We see some correspondences with the experimental data. Meanwhile, we have obtained diquark masses in the background of charm quark which satisfy a splitting relation based on spin-spin interaction.
