Three current models of QCD in (1+1) dimensions are examined and extended in light-front coordinates. A pion of high momentum is found to have an infinite extent along its direction of motion.

  1. Gluon skewed generalized parton distributions of proton from a light-front Hamiltonian approach

    hep-ph 2025-01 conditional novelty 5.0 of 10

    Using light-front wave functions with one dynamical gluon, the authors obtain all leading-twist gluon GPDs of the proton at nonzero skewness and find diffraction-like patterns in longitudinal position space.

  2. 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.

  3. $\phi$-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.
