Description
Confinement and chiral symmetry breaking are the two fundamental aspects of QCD in the non-perturbative regime. Yet, our understanding of the two remains incomplete to this date. In this talk, I will show how they can be understood within the semi-classical approach to QCD, light-front holography (LFH). I will further show that chiral symmetry breaking in LFH is consistent with a rigorous sum rule derived from the partially conserved axial-vector current (PCAC) and the general Lorentz structure of the pion. Within the same holographic model, the Goldstone boson shows some remarkable feature: it is mostly uniform within. The implication to ab initio LFQCD will also be mentioned.
