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…
Projecting the Bethe-Salpeter Equation onto the Light-Front and back: A Short Review
Tobias Frederico, Giovanni Salme`
The technique of projecting the four-dimensional two-body Bethe-Salpeter equation onto the three-dimensional Light-Front hypersurface, combined with the quasi-potential approach, i…
Nucleon-nucleon scattering within a multiple subtractive renormalization approach
V. S. Timoteo, T. Frederico, A. Delfino +1
A methodology to renormalize the nucleon-nucleon interaction, using a recursive multiple subtraction approach to construct the kernel of the scattering equation, is presented. We s…
Spin and pseudospin symmetries in the antinucleon spectrum of nuclei
R. Lisboa, M. Malheiro, P. Alberto +2
Spin and pseudospin symmetries in the spectra of nucleons and antinucleons are studied in a relativistic mean-field theory with scalar and vector Woods-Saxon potentials, in which t…
Dirac-Brueckner Hartree-Fock Approach: from Infinite Matter to Effective Lagrangians for Finite Systems
Nguyen Van Giai, Brett V. Carlson, Zhongyu Ma +1
One of the open problems in nuclear structure is how to predict properties of finite nuclei from the knowledge of a bare nucleon-nucleon interaction of the meson-exchange type. We…
Compact stars with a quark core within NJL model
C. H. Lenzi, A. S. Schneider, C. Providência +1
An ultraviolet cutoff dependent on the chemical potential as proposed by Casalbuoni {\it et al} is used in the su(3) Nambu-Jona-Lasinio model. The model is applied to the descripti…
