Stress inside the pion in holographic light-front QCD

Abstract

In this work, we propose a method to compute the gravitational form factor $D(Q^2)$ in holographic QCD by exploiting 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. As an application, we compute the $D$-term for the pion, and compare the results with recent lattice simulations.
