Generalized Supersymmetric Cosmological Term in N=1 Supergravity |
|
Abstract |
An alternative way of introducing a cosmological term in a supergravity theory is presented. We show that the AdS-Lorentz superalgebra allows to construct a geometric formulation of supergravity containing a generalized cosmological constant. The N=1 D=4 supergravity action is constructed out of the two-form curvatures for the AdS-Lorentz superalgebra and corresponds to a MacDowell-Mansouri like action. |
