讲座内容：

We utilize modern dispersion analysis to investigate the gravitational form factors of nucleons, achieving precise determinations that closely agree with recent lattice QCD results. Our systematic calculations of various three-dimensional spatial and two-dimensional transverse density distributions offer new insights into the nucleons' mass distributions. Additionally, as a byproduct, we make a match between our dispersion relation results to the chiral perturbation theory at NNLO, yielding values for the low-energy constants c8 and c9. These advancements establish a solid benchmark for future experimental and theoretical studies.
