Assuming Regge trajectories in holographic QCD: from OPE to Chiral Perturbation Theory
The Soft Wall model in holographic QCD has Regge trajectories but wrong operator product expansion (OPE) for the two-point vectorial QCD Green function. We correct analytically this problem and describe the axial sector and chiral symmetry breaking. The low energy chiral parameters, $F_{\pi}$ and $L...
