  1. 28. Asymptotic freedom of gluons in Hamiltonian dynamics
    Dr Maria Gomez-Rocha (University of Graz)
    22/09/2015, 16:30
    Oral contribution
    Asymptotic freedom of gluons in QCD is obtained in the leading terms of their renormalized Hamiltonian in the Fock space. We calculate the three-gluon interaction term in the front-form Hamiltonian for gluons using the renormalization group procedure for effective particles (RGPEP). The resulting three-gluon vertex is a function of the scale parameter, $s$, that has an interpretation of the...

  2. 18. The electron in three-dimensional momentum space
    Luca Mantovani (PV)
    22/09/2015, 16:50
    Oral contribution
    We study the electron at order alpha as a system composed by an electron and a photon within the framework of light-front quantization. We derive the leading-twist transverse-momentum dependent distribution functions for both the electron and photon in the dressed electron, using different gauge prescriptions. In particular, we discuss the light-cone gauge and the Feynman gauge, applying both...

  3. 61. Light - Front Wave Function for Hadrons with arbitrary twist
    Dr Alfredo Vega (Universidad de Valparaiso)
    22/09/2015, 17:10
    Oral contribution
    Based on the matching of soft wall AdS / QCD models and Light - Front QCD for electromagnetic form factors, we derive a phenomenological wave function for hadrons with arbitrary twist dimension. We discuss a couple of examples of hadron properties calculated with this wave function.

  4. 6. Light Front Perturbation without Spurious Singularities
    Dr Jerzy A. Przeszowski (Faculty of Physics, University of Bialystok)
    22/09/2015, 17:30
    Oral contribution
    A new form of the light front Feynman propagators is proposed. It contains no energy denominators. Instead the dependence on the longitudinal subinterval x^2_L = 2 x^{+} x^{-} is explicit and a new formalism for doing the perturbative calculations is invented. These novel propagators are implemented for the one-loop scattering matrix for a massive scalar field. The consistency with...
