Deep inelastic scattering off scalar mesons in the 1/N expansion from the D3D7-brane system
arXiv:1609.01202
Abstract
Deep inelastic scattering (DIS) of charged leptons off scalar mesons in the expansion is studied by using the gauge/gravity duality. We focus on the D3D7-brane system and investigate the corresponding structure functions by considering both the high energy limit and the expansion. These limits do not commute. From the D7-brane DBI action we derive a Lagrangian at sub-leading order in the D7-brane fluctuations and obtain a number of interactions some of which become relevant for two-hadron final-state DIS. By considering first the high energy limit followed by the large one, our results fit lattice QCD data within for the first three moments of for the lightest pseudoscalar meson.
