Energy-Momentum Tensor and D-term of Baryons in Top-down Holographic QCD

Abstract

We study the energy-momentum tensor of a baryon in a top-down holographic QCD. In holographic QCD, the baryons are represented as solitons in a 5-dimensional gauge theory. We obtain the soliton solution by solving the equations of motion numerically. Using this result, the energy-momentum tensor and related quantities such as the mass, mean square radii, and the D-term (druck term) are computed. The evaluated D-term is about -2.05, whose absolute value is significantly larger than that in the previous work arXiv:2206.06578.
