Bound States of Spinless Particles in a Short-Range Potential
(Walter De Gruyter Gmbh, 2015-04-01)
With a general mixing of vector and scalar couplings in a two-dimensional world, a short-range potential is used to explore certain features of the bound states of a spinless particle. Bound-state solutions are found in ...
Astrophysical constraints on a light spinless particle coupled to photons
(1996-12-01)
We examine further astrophysical constraints on a light spinless particle coupled only to photons and proposed by Massó and Toldra. We consider constraints coming from measurements of extra galactic background and from ...

Estados estacionários de partículas sem spin em potenciais quadrados
(2008-11-06)
The one-dimensional Klein-Gordon equation is investigated with the most general Lorentz structure for the external potentials. The analysis and calculation of the reflection and transmission coeffifients for the scattering ...
Effects of a mixed vector-scalar kink-like potential for spinless particles in two-dimensional space time
(World Scientific Publ Co Pte Ltd, 2007-06-20)
The intrinsically relativistic problem of spinless particles subject to a general mixing of vector and scalar kink- like potentials (similar to tanh gamma x) is investigated. The problem is mapped into the exactly solvable ...
Effects of a mixed vector-scalar screened coulomb potential for spinless particles
(World Scientific Publ Co Pte Ltd, 2006-10-10)
The problem of a spinless particle subject to a general mixing of vector and scalar screened Coulomb potentials in a two-dimensional world is analyzed and its bounded solutions are found. Some unusual results, including ...
Confinement of spinless particles by Coulomb potentials in two-dimensional space-time
(Elsevier B.V., 2005-10-10)
The problem of confinement of spinless particles in 1 + 1 dimensions is approached with a linear potential by considering a mixing of Lorentz vector and scalar couplings. Analytical bound-states solutions are obtained when ...
Scattering and bound states of spinless particles in a mixed vector-scalar smooth step potential
(Academic Press Inc. Elsevier B.V., 2009-11-01)
Scattering and bound states for a spinless particle in the background of a kink-like smooth step potential, added with a scalar uniform background, are considered with a general mixing of vector and scalar Lorentz structures. ...
