Predicting a new resonance as charmed-strange baryonic analog of $D_{s0}^*(2317)$

TL;DR

This paper predicts a new charmed-strange baryon state using an unquenched quark model, suggesting it could be observed in future experiments and serving as an analog to a known meson.

Contribution

The study introduces a novel prediction of a charmed-strange baryon state with a specific mass, highlighting its potential as an analog to a known meson and suggesting experimental search strategies.

Findings

Predicted mass of the baryon state is 2945 MeV.

The state is below the $\Xi_car{K}$ threshold due to coupled-channel effects.

Potential for experimental detection in the $\Omega_c^{(*)}\gamma$ spectrum.

Abstract

By an unquenched quark model, we predict a charmed-strange baryon state, namely, the $\Omega_{c0}^d(1P,1/2^-)$. Its mass is predicted to be 2945 MeV, which is below the $\Xi_c\bar{K}$ threshold due to the nontrivial coupled-channel effect. So the $\Omega_{c0}^d(1P,1/2^-)$ state could be regraded as the analog of the charmed-strange meson $D_{s0}^*(2317)$. It is a good opportunity for the running Belle II experiment to search for this state in the $\Omega_c^{(*)}\gamma$ mass spectrum experiment in the future.
