A look inside charmed-strange baryons from lattice QCD

Understand

The electromagnetic form factors of the spin-3/2 $\Omega$ baryons, namely $\Omega$, $\Omega_c^\ast$, $\Omega_{cc}^\ast$ and $\Omega_{ccc}$, are calculated in full QCD on $32^3\times 64$ 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 for the electric quadrupole form factors, $E2$, are also given.
• Quark sector contributions are computed individually for each observable and then combined to obtain the baryon properties.
