Hadronic structure on the light-front. VII. Pions and kaons and their partonic distributions

This work is a continuation in our series of papers, that addresses quark models hadronic structure on the light front, motivated by QCD vacuum and lattice results. The spontaneous breaking chiral symmetry shown to parallel rest frame, where non-local instanton induced $^\prime$t Hooft interaction plays central role. By rewriting this solely terms good component fermionic field, scalar condensate emerges mean-field approximation, which identical one obtained frame. pions kaons emerge as deeply bound Goldstone modes limit, with scalar-isoscalar sigma meson mode threshold state zero binding. We explicitly derive front distribution amplitudes (DAs) partonic functions (PDFs) for these mesons. DAs PDFs are agreement those extracted from using large momentum effective theory (LaMET). evolved compare well available measurements, recent
