Gravitational baryogenesis in DGP brane cosmology

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
We consider the imbalance of matter and antimatter by using a gravitational baryogenesis mechanism in the background of Dvali–Gabadadze–Porrati (DGP) brane cosmology.

Four-dimensional Brane–Chern–Simons Gravity and Cosmology

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
From the field equations corresponding to a four-dimensional brane embedded in the five-dimensional spacetime of the Einstein–Chern–Simons theory for gravity, we find cosmological solutions that describe an accelerated expansion for a flat universe ...

S-BRANES, NEGATIVE TENSION BRANES AND COSMOLOGY [PDF]

open access: yesString Phenomenology, 2003
A general class of solutions of string background equations is studied and its physical interpretations are presented. These solutions correspond to generalizations of the standard black p-brane solutions to surfaces with curvature k=-1,0. The relation with the recently introduced S-branes is provided.

Anisotropic SD2 brane: accelerating cosmology and Kasner-like space-time from compactification

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
Starting from an anisotropic (in all directions including the time direction of the brane) non-SUSY D2 brane solution of type IIA string theory we construct an anisotropic space-like D2 brane (or SD2 brane, for short) solution by the standard trick of a ...

Some Aspects of String Cosmology and the LHC

open access: yesEPJ Web of Conferences, 2014
I discuss some (unconventional) aspects of String Cosmology of relevance to super symmetric dark matter searches at the Large Hadron Collider (LHC) at CERN.

Cosmology from quantum potential in brane–anti-brane system

open access: yesPhysics Letters B, 2015
Recently, some authors removed the big-bang singularity and predicted an infinite age of our universe. In this paper, we show that the same result can be obtained in string theory and M-theory; however, the shape of universe changes in different epochs ...

A domain wall description of brane inflation and observational aspects

open access: yesPhysics Letters B, 2020
We consider a brane cosmology scenario by taking an inflating 3D domain wall immersed in a five-dimensional Minkowski space in the presence of a stack of N parallel domain walls.
