# Electromagnetic form factors of the baryon decuplet with flavor SU(3) symmetry breaking

## TL;DR

This paper calculates the electromagnetic form factors of the baryon decuplet using a chiral quark-soliton model, incorporating SU(3) symmetry breaking, and finds good agreement with recent lattice QCD data.

## Contribution

It introduces a self-consistent SU(3) chiral quark-soliton model that includes symmetry breaking and rotational corrections to study baryon decuplet form factors.

## Key findings

- Results agree well with recent lattice QCD data.
- Charge and magnetic radii, moments, and quadrupole moments are computed and compared.
- Form factors show similar trends to lattice results, especially for M1 and E2.

## Abstract

We investigate the electromagnetic form factors of the baryon decuplet within the framework of the $\mathrm{SU(3)}$ self-consistent chiral quark-soliton model, taking into account the $1/N_c$ rotational corrections and the effects of flavor $\mathrm{SU(3)}$ symmetry breaking. We first examine the valence- and sea-quark contributions to each electromagnetic form factor of the baryon decuplet and then the effects of the flavor SU(3) symmetry breaking. The present results are in good agreement with the recent lattice data. We also compute the charge radii, the magnetic radii, the magnetic dipole moments and the electric quadrupole moments, comparing their results with those from other theoretical works. We also make a chiral extrapolation to compare the present results with the lattice data in a more quantitative manner. The results show in general similar tendency to the lattice results. In particular, the results of the $M1$ and $E2$ form factors are in good agreement with those of lattice QCD.
