A note on \Xi_c(3055)^+ and \Xi_c(3123)^+

TL;DR

This paper investigates the properties of two newly observed excited charmed baryons, analyzing their decay modes under D-wave assumptions to help identify their quantum states and guide future experimental studies.

Contribution

It provides a theoretical analysis of the strong decays of (3055)^+ and (3123)^+ assuming D-wave states, excluding some assignments and proposing decay modes for further investigation.

Findings

Some D-wave state assignments are excluded based on decay width comparisons.

Suggested decay modes to aid experimental determination of baryon properties.

Provided theoretical decay width estimates consistent with experimental data.

Abstract

Babar Collaboration announced two new excited charmed baryons $\Xi_c(3055)^+$ and $\Xi_c(3123)^+$. We study their strong decays assuming they are D-wave states. Some assignments are excluded by comparing our numerical results with the experimental values of the total widths of $\Xi_c(3055)^+$ and $\Xi_c(3123)^+$. We also suggest some possible decay modes, which will be helpful to determine the properties of $\Xi_c(3055)^+$ and $\Xi_c(3123)^+$.
