摘要：

We show that the holographic Schodinger equation of light-front chiral QCD, together with the t Hooft equation of (1+1)-dimensional QCD in the large Nc limit, can simultaneously describe pion spectroscopy as well as the pion decay constant, charge radius, electromagnetic form factor, photon-to-pion transition form factor, Parton Distribution Function (PDF) and Distribution Amplitude (DA). Furthermore, the chiral -limit constraints, as encoded in the Gell-Mann-Oakes-Renner (GMOR) relation, are satisfied. (c) 2022 The Author(s). Published by Elsevier B.V.
