Description
The electromagnetic form factors (EMFFs) $G_E$ and $G_M$ of hadrons are fundamental quantities for probing the internal structure of hadrons and understanding the perturbative and nonperturbative quantum chromodynamics(QCD) effects encoded in hadrons. They contain the
information about the distribution of electric charge and magnetic moment of the hadron.
In the present work, we investigate the medium modifications of the EMFFs of the $\Sigma$ hyperons in nuclear matter using the vector meson dominance model. The in-medium effects are incorporated through density-dependent vector meson masses obtained from QCD sum rules and chiral SU(3) quark mean-field model, along with the medium modified $\Sigma$ effective mass. The sensitivity of EMFFs of $\Sigma$ with baryon density may help to probe the internal structure of baryons in extreme environments.
