  • Light-front Ward-Takahashi identity and current conservation 
    Marinho, J.A.O.; Frederico, T.; Sauer, P.U. (College Park, MD : American Physical Society, 2007)
    We construct a conserved electromagnetic current for two-boson systems in finite mass boson exchange models within light-front dynamics. For that purpose, we use a quasipotential reduction to perform the three-dimensional ...
  • Renormalization of the ladder light-front Bethe-Salpeter equation in the Yukawa model 
    Sales, J.H.O.; Frederico, T.; Carlson, B.V.; Sauer, Peter Ulrich (College Park, MD : American Physical Society, 2001)
    The reduction of the two-fermion Bethe-Salpeter equation in the framework of light-front dynamics is studied for the Yukawa model. It yields auxiliary three-dimensional quantities for the transition matrix and the bound ...
