Description
The hadronic energy-momentum tensor encodes the energy and stress distributions within hadrons. In this talk, I will report our recent advancements on the computation of gravitational form factor D(Q^2) in holographic QCD. Our method exploits the remarkable correspondence between semi-classical light-front QCD and semi-classical field theories in wrapped spacetime in 5D. The use of light-front holography bridges physics at large Q^2 as attained in light-front QCD and physics at small Q^2 where the coupling to scalar and tensor fields, i.e. glueballs, are dominant. We also compare our results with the recent lattice simulation.
