Description
The light-front wave functions (LFWF) of hadrons can be obtained by projecting their Bethe-Salpeter wave functions on the light front. The latter is obtained within a functional approach to QCD, solving first the quark gap equation within a chiral-symmetry preserving truncation scheme and then the Bethe-Salpeter equation for pseudoscalar and vector mesons. With the LFWF we derive the meson’s parton distribution function (PDF), transverse momentum distribution (TMD) and generalized parton distributions (GPD) of light and heavy mesons as well as quarkonia. Quark-fragmentation functions and their generalization to jet functions are obtained within the same framework. The insights of these studies serve to prepare the field for nucleons, which are the real object of interest at the EIC.
