Description
Gravitational form factors are defined as the matrix elements of the energy-momentum tensor. Being closely connected to the origin of the visible matter mass, they have attracted significant attention in recent years. I will discuss the investigation of gravitational form factors of pions, kaons and the nucleons employing dispersive techniques and chiral perturbation theory, and present model-independent results at both physical and unphysical quark masses.
