Inflation in supergravity with non-minimal superpotentials
G. A. Diamandis, B. C. Georgalas, K. Kaskavelis +3
We investigate the cosmological inflation in a class of supergravity models that are generalizations of non-supersymmetric models. Although such models have been extensively…
Six-dimensional origin of gravity mediated brane to brane supersymmetry breaking
G. A. Diamandis, B. C. Georgalas, P. Kouroumalou +1
Four dimensional supergravities may be the right framework to describe particle physics at low energies. Its connection to the underlying string theory can be implemented through h…
Six-Dimensional Jordan Supergravity Models
P. Kouroumalou
In the context of six-dimensional supergravity there is a special class of parent models for five-dimensional theories defined by the four Euclidean simple Jordan algebras of degre…
The soft supersymmetry breaking in D=5 supergravity compactified on S_1/Z_2 orbifolds
G. A. Diamandis, B. C. Georgalas, P. Kouroumalou +1
We study the origin of the supersymmetry breaking induced by the mediation of gravity and the radion multiplet from the hidden to the visible brane in the context of the N=2, D=5 s…
On the radion mediation of the Supersymmetry breaking in N=2, D=5 Supergravity Orbifolds
G. A. Diamandis, B. C. Georgalas, P. Kouroumalou +1
We discuss the on-shell N=1 Supersymmetric coupling of brane chiral multiplets in the context of N=2, D=5 Supergravity compactified on orbifolds. Assuming a constant supe…
On the brane coupling of Unified orbifolds with gauge interactions in the bulk
G. A. Diamandis, B. C. Georgalas, P. Kouroumalou +1
In the on-shell formulation of , N=2 supergravity, compactified on , we extend the results of Mirabelli and Peskin describing the interaction of the bulk fields with…
On the Stability of the Classical Vacua in a Minimal SU(5) 5-D Supergravity Model
G. A. Diamandis, B. C. Georgalas, P. Kouroumalou +1
We consider a five-dimensional supergravity model with SU(5) gauge symmetry and the minimal field content. Studying the arising scalar potential we find that the gauging of the $U(…
