A holographic analysis of the pion

High Energy Physics - Phenomenology 2025-08-19 v1

Abstract

Being simultaneously a bound state and a pseudo-Goldstone boson of chiral symmetry breaking, the pion is an ideal probe of the intertwined phenomena of confinement and chiral symmetry breaking in QCD. Here, we compute the low energy pion observables with light-front holography, taking into account longitudinal dynamics using an ansatz that explores the strong degeneracy of the `t Hooft and Li-Vary models as well as their underlying connection in AdS3\mathrm{AdS}_3 as recently noted by Vegh.
