Study of Charm Baryons with the BaBar Experiment

TL;DR

This paper reports on charm baryon production and decay studies using the BaBar experiment, confirming previous observations, measuring branching ratios, and exploring properties of light-quark baryons.

Contribution

It provides new measurements of branching ratios and confirms the existence of several charm baryons, enhancing understanding of charm baryon spectroscopy.

Findings

Confirmed observations of $\\Xi_c^{'0/+}$, $\\Xi_c(2980)^+$, and $\\Xi_c(3077)^+$ baryons

Measured branching ratios for Cabibbo-suppressed $\\Lambda_c^+$ decays

Studied properties of $\\Omega^-$ and $\\Xi(1690)^0$ baryons

Abstract

We report on several studies of charm baryon production and decays by the BaBar collaboration. We confirm previous observations of the $\Xi_c^{'0/+}$, $\Xi_c(2980)^+$ and $\Xi_c(3077)^+$ baryons, measure branching ratios for Cabibbo-suppressed $\Lambda_c^+$ decays and use baryon decays to study the properties of the light-quark baryons, $\Omega^-$ and $\Xi(1690)^0$.
