Absence of resonant decay for metastable vacua in gauge theories of scalar fields
M. Cardella, S. Elitzur, E. Rabinovici
We prove the impossibility of resonant decay of a metastable vacuum in a theory of a scalar field coupled to a gauge field. Our result extends to gauge theories of scalar fields a…
An Alternative for Moduli Stabilisation
C. Angelantonj, M. Cardella, N. Irges
The one-loop vacuum energy is explicitly computed for a class of perturbative string vacua where supersymmetry is spontaneously broken by a T-duality invariant asymmetric Scherk-Sc…
Mechanisms for Supersymmetry Breaking in Open String Vacua
Matteo A. Cardella
We investigate mechanisms that can trigger supersymmetry breaking in open string vacua. The focus is on backgrounds with D-branes and orientifold planes that have an exact string d…
Vanishing Perturbative Vacuum Energy in Non-Supersymmetric Orientifolds
Carlo Angelantonj, Matteo Cardella
We present a novel source for supersymmetry breaking in orientifold models, and show that it gives a vanishing contribution to the vacuum energy at genus zero and three-half. We al…
