We propose a novel scenario for Affleck-Dine baryogenesis in the braneworld, considering the hybrid potential for the Affleck-Dine field. Destabilization of the flat direction is not due to the Hubble parameter, but is induced by a trigger field. The moduli for the brane distance plays the role of the trigger field. Q-balls are unstable in models with large extra dimensions.

A bstract Recently, boundary conformal field theories (BCFTs) have attracted much attention in the context of quantum gravity. This is because a BCFT can be dual to gravity coupled heat bath CFT, known as island model. On this background, it would interesting explore duality between and braneworld. However, seems challenging problem. The reason although there has been study rational BCFTs, comp...

Modifications to the Friedmann equation in brane cosmology can have important implications for early universe phenomena such as inflation and the generation of the baryon asymmetry. In the framework of braneworld cosmology, we discuss a mechanism for baryogenesis via leptogenesis in the supersymmetric context, where the sneutrino is responsible for both inflation and the generation of the baryo...

We study a codimension 2 braneworld in the Einstein-Gauss-Bonnet gravity. In the linear regime, we show the conventional Einstein gravity can be recovered on the brane. While, in the nonlinear regime, we find corrections due to the thickness and the bulk geometry.

We investigate the cosmological dynamics of a brane Universe when quantum corrections from vacuum polarization are taken into account. New vacuum de Sitter points existing on Randall-Sundrum brane are described. We show also that quantum correction can destroy the DGP de Sitter solution on induced gravity brane. † Electronic mail: [email protected] ‡ Electronic mail: [email protected] Investig...

In this paper we explicitly work out the secular perturbations induced on all the Keplerian orbital elements of a test body to order O(e2) in the eccentricity e by the weak-field long-range modifications of the usual Newton-Einstein gravity due to the Dvali-Gabadadze-Porrati (DGP) braneworld model. Both the Gauss and the Lagrange perturbative schemes are used. It turns out that the argument of ...

We study cosmological implications of a Lorentz invariance violating DGPinspired braneworld scenario. A minimally coupled scalar field and a single, fixednorm, Lorentz-violating timelike vector field within an interactive picture provide a wide parameter space which accounts for late-time acceleration and transition to phantom phase of the scalar field.

Abstract In this article, the possibility of construction a traversable wormhole on Randall–Sundrum braneworld with non-exotic matter employing Kuchowicz potential has been studied. We have obtained solution for shape function and studied its properties along validity null energy condition. The junction conditions at surface are used to evaluate model parameters. also density pressure wormhole....
