General Relativity from a gauged WZW term
Andres Anabalon, Steven Willison, Jorge Zanelli
In this paper two things are done. First it is shown how a four dimensional gauged Wess-Zumino-Witten term arises from the five dimensional Einstein-Hilbert plus Gauss-Bonnet lagra…
N=4 superconformal mechanics as a Non linear Realization
Andres Anabalon, Joaquim Gomis, Kiyoshi Kamimura +1
An action for a superconformal particle is constructed using the non linear realization method for the group PSU(1,1|2), without introducing superfields. The connection between PSU…
Asymptotic behavior and Hamiltonian analysis of anti-de Sitter gravity coupled to scalar fields
Marc Henneaux, Cristian Martinez, Ricardo Troncoso +1
We examine anti-de Sitter gravity minimally coupled to a self-interacting scalar field in dimensions when the mass of the scalar field is in the range $m_{\ast}^{2}\leq m…
Dynamics and BPS states of AdS5 supergravity with a Gauss-Bonnet term
Olivera Miskovic, Ricardo Troncoso, Jorge Zanelli
Some dynamical aspects of five-dimensional supergravity as a Chern-Simons theory for the SU(2,2|N) group, are analyzed. The gravitational sector is described by the Einstein-Hilber…
Transgression forms and extensions of Chern-Simons gauge theories
Pablo Mora, Rodrigo Olea, Ricardo Troncoso +1
A gauge invariant action principle, based on the idea of transgression forms, is proposed. The action extends the Chern-Simons form by the addition of a boundary term that makes th…
