Abstract |
The deformation of the super-anti-de Sitter algebra by adding additional generators, will be presented. That kind of deformation is forming the negative cosmological constant counterpart of the Maxwell algebra.The procedure of gauging this algebra and construction of a dynamical model will be done in the frame of the BF theory of MacDowell-Mansouri type. It turns out that the resulting theory is described by the Einstein-Cartan action with Holst term, and the gauge fields associated with the Maxwell generators influence only the topological term, which can be interpreted as a “topological vacuum”. This enlarging of the super-anti-de Sitter algebra is a promising toy model to contract unified gauge theory of gravity and Yang-Mills interaction. |
