Look inside charmed-strange baryons from lattice QCD

The electromagnetic form factors of the spin-$3/2$ $\mathrm{\ensuremath{\Omega}}$ baryons, namely $\mathrm{\ensuremath{\Omega}}$, ${\mathrm{\ensuremath{\Omega}}}_{c}^{*}$, ${\mathrm{\ensuremath{\Omega}}}_{cc}^{*}$ and ${\mathrm{\ensuremath{\Omega}}}_{ccc}$, are calculated in full QCD on ${32}^{3}\ifmmode\times\else\texttimes\fi{}64$ PACS-CS lattices with a pion mass of 156(9) MeV. The electric charge radii and magnetic moments from the $E0$ and $M1$ multipole form factors are extracted. Results
