Gravitational form factors of the singly heavy baryon Σc

초록

In this talk, we present results of the gravitational form factors of the singly heavy baryon Σc within the framework of a pion mean-field approach. We discuss how the pressure of the Σc can nontrivially vanish in the pion mean-field approach. We computed three different form factors, i.e., the mass form factor, D-term form factor, and the form factor of the angular momentum. In order to compare future results from lattice QCD, we employ the values of the unphysical pion mass and discuss the dependence of the form factors on it. We also present the mechanical equation of the states, i.e. the relation between the pressure and mass densities.
