AB A unified set of predictions for pion, kaon and nucleon gravitational form factors is obtained usinga symmetry-preserving truncation of each relevant quantum field equation. A crucial aspect of thestudy is the self-consistent characterization of the dressed quark-graviton vertices, applied whenprobing each quark flavor inside mesons or nucleons. The calculations reveal that each hadron’smass radius is smaller than its charge radius, matching available empirical inferences; moreover,core pressures are significantly greater than those in neutron stars. This set of predictions isexpected to be instrumental as forthcoming experiments provide opportunities for validation.
