Deconfined SU(2) phase with a massive vector boson triplet
Deconfined SU(2) phase massive vector boson triplet
2010/12/27
We introduce a model of SU(2) and U(1) vector fields with a local U(2) symmetry. Its action can be obtained in the London limit of a gauge invariant regularization involving two scalar fields. Evidenc...
Bound states of the Duffin-Kemmer-Petiau equation with a mixed minimal-nonminimal vector cusp potential
Bound states the Duffin-Kemmer-Petiau equation
2010/12/23
The problem of spin-0 and spin-1 bosons subject to a general mixing of minimal and nonminimal vector cusp potentials is explored in a unified way in the context of the Duffin-Kemmer-Petiau theory. Eff...
A note on the vector Schwinger Model with the photon mass term: Gauge invariant reformulation, operator solution and path integral formulation
vector Schwinger Model photon mass term
2010/12/23
Vector Schwinger model is reinvestigated with the mass like term for gauge field. Phase space structure has been determined in this situation. It has been found that mass of the gauge boson acquires ...
Particle Production of Vector Fields: Scale Invariance is Attractive
Particle Production Vector Fields Scale Invariance
2010/12/27
In a model of an Abelian vector boson with a Maxwell kinetic term and non-negative mass-squared it is demonstrated that, under fairly general conditions during inflation, a scale-invariant spectrum of...
Green's Function expansion of scalar and vector fields in the presence of a medium
Green's Function expansion scalar and vector fields presence of a medium
2010/11/5
Based on a canonical approach and functional-integration techniques, a series expansion of Green's function of a scalar field, in the presence of a medium, is obtained. A series expansion for Lifshitz...
