Effects of the Lorentz symmetry violation on relativistic neutral scalar bosons: Scattering and bound states
Luis B. Castro, Antonio S. de Castro
In this letter, we investigate the effects of Lorentz symmetry violation on a relativistic neutral scalar boson within the framework of the Klein-Gordon formalism. We consider a te…
On the electromagnetic interaction and the anomalous term in the Duffin-Kemmer-Petiau theory
Andrés G. Jirón, Luis B. Castro, Antonio S. de Castro +1
The problem of vectorial mesons embedded in an electromagnetic field via Duffin-Kemmer-Petiau (DKP) formalism is reinvestigated. Considering the electromagnetic interaction as a mi…
Proper treatment of scalar and vector exponential potentials in the Klein-Gordon equation: Scattering and bound states
Elvis J. Aquino Curi, Luis B. Castro, Antonio S. de Castro
We point out a misleading treatment in the literature regarding to bound-state solutions for the -wave Klein-Gordon equation with exponential scalar and vector potentials. Follo…
Solutions of the three-dimensional radial Dirac equation from the Schrödinger equation with one-dimensional Morse potential
M. G. Garcia, A. S. de Castro, P. Alberto +1
New exact analytical bound-state solutions of the radial Dirac equation in 3+1 dimensions for two sets of couplings and radial potential functions are obtained via mapping onto the…
Fermions in a mixed vector-scalar double-step potential via continuous chiral transformation
W. M. Castilho, A. S. de Castro
The behaviour of fermions in the background of a double-step potential is analyzed with a general mixing of scalar and vector couplings via continuous chiral-conjugation transforma…
Fermions embedded in a scalar-vector kink-like smooth potential
W M Castilho, A S de Castro
The behaviour of massive fermions is analyzed with scalar and vector potentials. A continuous chiral-conjugation transformation decouples the equation for the upper component of th…
