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...

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...

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.

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...
