Description
In the present talk, we review recent work on the gravitational form factors (GFFs) and the energy-momentum tensor (EMT) distributions of the baryon octet. Based on the SU(3) chiral quark-soliton model, we first examine the effects of flavor SU(3) symmetry breaking on the GFFs. We observe that a heavier hyperon is energetically more compact than a lighter one. We also show that the spin distribution of the octet baryon can be decomposed into the quark components (singlet axial charges) and the quark angular momentum ones. We discuss the pressure and shear-force densities in three dimensional Breit frame. Then, we bring them to the infinite momentum frame (IMF) by implementing the IMF Abel transformation. Finally, we present the results for the EMT distributions of the singly heavy baryons and discuss their physical implications.
