Aspects of gauged R-symmetry in SU(1,1)/U(1) supergravity

Abstract
We propose a novel realization of spontaneous supersymmetry breaking in de Sitter vacuum by F- and D-terms in four-dimensional supergravity coupled to a chiral superfield with target space. Our construction features gauged symmetry rotating the chiral scalar field by a phase. Both SUSY and R-symmetry can be spontaneously broken, and for two particular parameter choices we obtain no-scale supergravity with positive tunable cosmological constant.
