| dc.description | We present a (unique?) possibility of de Sitter solution in the framework of N=2 supersymmetry (hypersymmetry). We show that a model with a vector and a charged hypermultiplet has a hybrid inflation type potential. It leads to a slow-roll regime in de Sitter type background with all supersymmetries broken spontaneously. Beyond the bifurcation point the waterfall stage abruptly brings the system into a ground state with 2 unbroken supersymmetries. De Sitter stage exists under condition that the superconformal SU(2,2|2) symmetry of the model is softly broken down to N=2 supersymmetry by the vev of the Killing prepotential triplet P^r. This hybrid hypersymmetry model may describe P-term inflation and/or acceleration of the universe at the present epoch. | |
