Covariant Derivation of Effective Actions for SUSY Topological Defects
Jordi París, Jaume Roca
We make a first step to extend to the supersymmetric arena the effective action method, which is used to covariantly deduce the low energy dynamics of topological defects directly…
A Remark on the Effective Description of Topological Defects
Jordi Paris, Jaume Roca
We subject the methodology used to derive the effective dynamics of topological defects to a critical reappraisal, using the two-dimensional kink as an illustrative example. Specia…
On the W-geometrical origins of massless field equations and gauge invariance
E. Ramos, J. Roca
We show how to obtain all covariant field equations for massless particles of arbitrary integer, or half-integer, helicity in four dimensions from the quantization of the rigid par…
On W_3-morphisms and the Geometry of Plane Curves
E. Ramos, J. Roca
We provide a description of W_3 transformations in terms of deformations of convex curves in two dimensional Euclidean space. This geometrical interpretation sheds some light on th…
Extended Gauge Invariance in Geometrical Particle Models and the Geometry of W-Symmetry
E. Ramos, J. Roca
We prove that particle models whose action is given by the integrated -th curvature function over the world line possess gauge invariances. A geometrical characterization…
Finite W_3 Transformations in a Multi-time Approach
J. Gomis, J. Herrero, K. Kamimura +1
Classical {\W} transformations are discussed as restricted diffeomorphism transformations (\W-Diff) in two-dimensional space. We formulate them by using Riemannian geometry as…
W-symmetry and the rigid particle
E. Ramos, J. Roca
We prove that $\W_3$ is the gauge symmetry of the scale-invariant rigid particle, whose action is given by the integrated extrinsic curvature of its world line. This is achieved by…
The W_3 particle
E. Ramos, J. Roca
We show that W_3 is the algebra of symmetries of the ``rigid-particle'', whose action is given by the integrated extrinsic curvature of its world line. This is easily achived by sh…
Particle Mechanics Models with W-symmetries
J. Gomis, J. Herrero, K. Kamimura +1
We introduce a particle mechanics model with Sp() gauge invariance. Different partial gauge-fixings by means of sl(2) embeddings on the gauge algebra lead to reduced models whi…
Zero-curvature condition in two dimensions. Relativistic particle models and finite \W-transformations
J. Gomis, J. Herrero, K. Kamimura +1
A relation between an gauge particle model and the zero-curvature condition in a two-dimensional gauge theory is presented. For the case we construct finite \W-tra…
