We present an analytically solvable 3D light-front Hamiltonian model for hadrons that extends light-front holography by including finite mass quarks and a longitudinal confinement term. We propose that the model is suitable as an improved analytic approximation to QCD at a low resolution scale. We demonstrate that it preserves desired Lorentz symmetries and it produces improved agreement with the experimental mass spectroscopy and other properties of the light mesons. Importantly, the model also respects chiral symmetry and the Gell-Mann-Oakes-Renner relation.

A holographic analysis of the pion
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.

$\phi$-meson spectroscopy and diffractive production using two Schr\"odinger like equations on the light-front
A two-equation light-front model reproduces the phi meson mass spectrum and HERA diffractive production cross sections, but underpredicts its decay constant.
