Tensionless spinning string: emergence of world-sheet torsion and covariant density of energy-momentum tensor
A. A/ Zheltukhin
The action of tensionless spinning string invariant under reparametrizions, both local supersymmetry and dilatations, is considered. The density of energy-momentum tensor is constr…
On possible composite structure of scalar fields in expanding universe
A. A. Zheltukhin
Scalar fields in curved backgrounds are assumed to be composite objects. As an example realizing such a possibility we consider a model of the massless tensor field in…
Brane mechanism of spontaneously generated gravity
A. A. Zheltukhin
The braneworld scenario is studied and the effective action of 3-brane living in 5-dim. Minkowski space is constructed. This action is proved to be invariant under spontaneously br…
-Branes with vacuum as models of gravity
A. A. Zheltukhin
Branes with constant mean curvature of their hyper-worldsheets of codim 1 are treated as the Nambu-Goldstone fields of the broken Poincare symmetry. Mapping of their action into qu…
Inflation versus collapse in brane matter
A. A. Zheltukhin
Mapping of fundamental branes to their worldsheet (ws) multiplets originating from spontaneous breaking of the Poincare symmetry is studied. The interaction Lagrangian for fields o…
Phenomenological Lagrangians, gauge models and branes
A. A. Zheltukhin
Phenomenological Lagrangians for physical systems with spontaneously broken symmetries are reformulated in terms of gauge field theory. Description of the Dirac -branes in terms…
