abstract

The breaking of chiral symmetry in holographic light-front QCD is encoded in its longitudinal dynamics with its chiral limit protected by the superconformal algebraic structure which governs its transverse dynamics. The scale in the longitudinal light-front Hamiltonian determines the confinement strength in this direction: It is also responsible for most of the light meson ground state mass consistent with the Gell-Mann-Oakes-Renner constraint. Longitudinal confinement and the breaking of chiral symmetry are found to be different manifestations of the same underlying dynamics as found in 't Hooft large $N_C$ QCD(1 + 1) model.

  1. A holographic analysis of the pion

    hep-ph 2024-12 conditional novelty 5.0 of 10

    The pion's measured mass, decay constant, and charge radius fix two longitudinal-potential models that then reproduce its measured electromagnetic and transition form factors at low Q^2.

  2. $\phi$-meson spectroscopy and diffractive production using two Schr\"odinger like equations on the light-front

    hep-ph 2025-01 conditional novelty 4.0 of 10

    A two-equation light-front model reproduces the phi meson mass spectrum and HERA diffractive production cross sections, but underpredicts its decay constant.
