Abstract

In this work, we propose a method to compute the gravitational form factor D(Q2) in holographic QCD by exploiting the remarkable correspondence between semiclassical light-front QCD and semiclassical field theories in wrapped spacetime in five dimensions. The use of light-front holography bridges physics at large Q2 as attained in light-front QCD and physics at small Q2 where the coupling to scalar and tensor fields, e.g. glueballs, are dominant. As an application, we compute the D-term for the pion and compare the results with recent lattice simulations.
