We investigate the cosmological inflation in a class of supergravity models that are generalizations of non-supersymmetric R2 models. Although such models have been extensively studied recently, especially after the launch of the PLANCK and BICEP2 da

We consider $R^2$ inflation in the Palatini gravity assuming the existence of scalar fields, coupled to gravity in the most general manner. These theories, in the Einstein frame, and for one scalar field $h$, share common features with $K$ - inflatio

We consider higher derivative supergravities that are dual to ghost-free $N=1$ supergravity theories in the Einstein frame. The duality is implemented by deforming the K\"ahler function, and/or the superpotential, to include nonlinear dependences on

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 supergravity compactified on S 1 / Z 2 orbifolds. The soft supersy

We discuss the on-shell N = 1 supersymmetric coupling of brane chiral multiplets in the context of N = 2 , D = 5 supergravity compactified on S 1 / Z 2 orbifolds. Assuming a constant superpotential on the hidden brane we study the transmission of the

We consider solutions of the cosmological equations pertaining to a dissipative, dilaton-driven off-equilibrium Liouville Cosmological model, which may describe the effective field theoretic limit of a non-critical string model of the Universe. The n

In the on-shell formulation of $D=5 $, N=2 supergravity, compactified on $S^1/Z_2$, we extend the results of Mirabelli and Peskin describing the interaction of the bulk fields with matter which is assumed to be confined on the brane. The novel charac

In this talk we discuss the impact of recent experimental information, like the revised bound from E821 Brookhaven experiment on gμ − 2 and light Higgs boson mass bound from LEP, in delineating regions of the parameters of the Constrained Minimal
