Light-front mass operator with dressed quarks
J. A. O. Marinho, J. P. B. C. de Melo, T. Frederico +1
We construct an effective light-front mass-squared operator for quark-antiquark systems that incorporates quark dressing effects through a running quark mass. Starting from a Minko…
Elastic electron-deuteron scattering and two-body current operators in the Light-Front Hamiltonian Dynamics
Tobias Frederico, J. Adnei Marinho, Emanuele Pace +1
The electromagnetic properties of the deuteron are investigated within a Light-Front Hamiltonian Dynamics framework, with a current operator that contains both one-body and two-bod…
Light-front projections of the Bethe-Salpeter amplitude and the 4D electromagnetic current for an interacting two-fermion system
T. Frederico, J. A. O. Marinho, E. Pace +1
A recent approach for constructing an exact 3D reduction of the 4D matrix elements of the electromagnetic current for an interacting two-fermion system, is briefly reviewed. The pr…
Revisiting the Wu-Yang Monopole: classical solutions and conformal invariance
J. A. O. Marinho, O. Oliveira, B. V. Carlson +1
he Wu-Yang monopole for pure SU(2) Yang-Mills theory is revisited. New classical solutions with finite energy are found for a generalized Wu-Yang configuration. Our method relies o…
Light-front Ward-Takahashi Identity for Two-Fermion Systems
J. A. O. Marinho, T. Frederico, E. Pace +2
We propose a three-dimensional electromagnetic current operator within light-front dynamics that satisfies a light-front Ward-Takahashi identity for two-fermion systems. The light-…
Semi-Analytical Analysis of Helium Synthesis in Brane Cosmology
J. C. Fabris, J. A. O. Marinho
The problem of primordial nucleosynthesis of helium in brane cosmology is studied using a semi-analytical method, where the Fermi-Dirac statistic is ignored. This semi-analytical m…
