A relativistic model for the Charmonium spectrum with a reduced number of free parameters
M. De Sanctis
A previously introduced reduction of the Dirac equation is used to study the Charmonium spectrum. A regularized vector potential that only depends on the coupling constant and on t…
A local reduction of the Dirac equation applied to the study of quark interactions
M. De Sanctis
A general procedure of local reduction for the Dirac equation is introduced to study one- and n-body interacting systems. In the one-body case we show that the reduction allows for…
Dirac shell quark-core model for the study of non-strange baryonic spectroscopy
Maurizio De Sanctis
A Dirac shell model is developed for the study of baryon spectroscopy, taking into account the most relevant results of the quark-diquark models. The lack of translational invarian…
Manifestly covariant current matrix elements in the Point Form Relativistic Hamiltonian Dynamics
M. De Sanctis
A manifestly covariant expression for the current matrix elements of three quark bound systems is derived in the framework of the Point Form Relativistic Hamiltonian Dynamics. The…
A covariant model of the electromagnetic current for the study of two-body scalar systems
Mario A. Acero, Maurizio De Sanctis, Carlos E. Sandoval
We present a procedure to derive a covariant electromagnetic current operator for a system made up by two scalars constituents. Using different wave functions we fitted their param…
Covariant Impulse Approximation for the study of the internal structure of composite particles
Maurizio De Sanctis, Mario A. Acero, Diego A. Milanes +1
We present a brief review on the Impulse Approximation method to study processes of scattering off composite particles. We first construct the model in a non-relativistic fashion t…
