The holographic graviton soft-wall model, introduced to describe the spectrum of scalar and tensor glueballs, is improved to incorporate the realization of chiral-symmetry as in QCD. Such a goal is achieved by including the longitudinal dynamics of QCD into the scheme. Using the relation between AdS/QCD and Light-Front dynamics, we construct the appropriate wave function for the pion which is used to calculate several pion observables. The comparison of our results with phenomenology is remarkably successful.

  1. Probing the chiral and $U(1)$ axial symmetry restoration via meson susceptibilities in holographic QCD

    hep-ph 2026-03 conditional novelty 5.0 of 10

    In a soft-wall holographic QCD model, chiral symmetry restores at ~155 MeV while the U(1) axial symmetry restores near 190 MeV — a separation the authors present despite an admitted mismatch with lattice QCD below 175 MeV.

  2. Dynamics of chiral phase transition in a $N_f=2+1$ soft-wall AdS/QCD model

    hep-ph 2025-07 conditional novelty 4.0 of 10

    In a 2+1 flavor soft-wall AdS/QCD model, the chiral condensate exhibits slow, non-trivial relaxation with a metastable plateau or overshoot when quenched close to the phase transition.
