No metastable de Sitter vacua in N=2 supergravity with only hypermultiplets
Marta Gomez-Reino, Jan Louis, Claudio A. Scrucca
We study the stability of vacua with spontaneously broken supersymmetry in N=2 supergravity theories with only hypermultiplets. Focusing on the projection of the scalar mass matrix…
Constructing de Sitter vacua in no-scale string models without uplifting
Laura Covi, Marta Gomez-Reino, Christian Gross +2
We develop a method for constructing metastable de Sitter vacua in N=1 supergravity models describing the no-scale volume moduli sector of Calabi-Yau string compactifications. We c…
Gaugino mass in AdS space
Ben Gripaios, Hyung Do Kim, Riccardo Rattazzi +2
We study supersymmetric QED in AdS4 with massless matter. At 1-loop the ultra-violet regulator of the theory generates a contribution to the gaugino mass that is naively inconsiste…
Constraints on modular inflation in supergravity and string theory
Laura Covi, Marta Gomez-Reino, Christian Gross +3
We perform a general algebraic analysis on the possibility of realising slow-roll inflation in the moduli sector of string models. This problem turns out to be very closely related…
Constraints from F and D supersymmetry breaking in general supergravity theories
Marta Gomez-Reino, Claudio A. Scrucca
We study the conditions under which a generic supergravity model involving chiral and vector multiplets can admit vacua with spontaneously broken supersymmetry and realistic cosmol…
de Sitter vacua in no-scale supergravities and Calabi-Yau string models
Laura Covi, Marta Gomez-Reino, Christian Gross +3
We perform a general analysis on the possibility of obtaining metastable vacua with spontaneously broken N=1 supersymmetry and non-negative cosmological constant in the moduli sect…
