Isospin Mass Differences of Heavy Baryons

TL;DR

This paper analyzes the isospin mass differences in heavy baryons, calculates the unmeasured neutral b-flavored sigma baryon mass, and questions the accuracy of existing charmed baryon mass difference measurements.

Contribution

It provides theoretical calculations for unmeasured baryon masses and highlights potential inaccuracies in previous experimental measurements.

Findings

Calculated the mass of the neutral b-flavored sigma baryon.

Suggested possible errors in measurements of charmed sigma and chi baryon mass differences.

Provided insights into isospin mass differences in heavy baryons.

Abstract

We discuss the mass differences for isospin multiplets of the charmed and b-flavored baryons. The mass of the neutral b-flavored sigma baryon, which is not measured, is calculated. We point out, that the measurements of the mass differences between the charmed sigma and chi baryons might be wrong.
