Scalar masses in general N=2 gauged supergravity theories
Francesca Catino, Claudio A. Scrucca, Paul Smyth
We readdress the question of whether any universal upper bound exists on the square mass m^2 of the lightest scalar around a supersymmetry breaking vacuum in generic N=2 gauged sup…
Simple metastable de Sitter vacua in N=2 gauged supergravity
Francesca Catino, Claudio A. Scrucca, Paul Smyth
We construct a simple class of N=2 gauged supergravity theories that admit metastable de Sitter vacua, generalizing the recent work done in the context of rigid supersymmetry. The…
Metastable spontaneous breaking of N=2 supersymmetry
Benoit Legeret, Claudio A. Scrucca, Paul Smyth
We show that contrary to the common lore it is possible to spontaneously break N=2 supersymmetry even in simple theories without constant Fayet-Iliopoulos terms. We consider the mo…
Metastable de Sitter vacua in N=2 to N=1 truncated supergravity
Francesca Catino, Claudio A. Scrucca, Paul Smyth
We study the possibility of achieving metastable de Sitter vacua in general N=2 to N=1 truncated supergravities without vector multiplets, and compare with the situations arising i…
Scalar geometry and masses in Calabi-Yau string models
Daniel Farquet, Claudio A. Scrucca
We study the geometry of the scalar manifolds emerging in the no-scale sector of Kahler moduli and matter fields in generic Calabi-Yau string compactifications, and describe its im…
The lightest scalar in theories with broken supersymmetry
Leonardo Brizi, Claudio A. Scrucca
We study the scalar mass matrix of general supersymmetric theories with local gauge symmetries, and derive an absolute upper bound on the lightest scalar mass. This bound can be sa…
