Warped Compactification with a Four-Brane
نویسنده
چکیده
Warped compactification of the six-dimensional bulk with a negative cosmological constant is realized with a 4-brane along with an abelian gauge theory. No fine tuning of couplings are needed to obtain the vanishing cosmological constant in four dimensions, as is the case for the bulk with a positive cosmological constant.

Warped Compactification with an Abelian Gauge Theory
We investigate warped compactification with an abelian gauge theory in six dimensions. The vanishing cosmological constant in four dimensions can generically be realized with a regular metric even in a 3-brane background without fine tuning of couplings.
متن کاملEffective warped brane-world compactification with a Gauss-Bonnet term
By including a Gauss-Bonnet interaction term into the brane-world effective action we give linear and non-linear treatments of the Einstein-Gauss-Bonnet gravity in warped spacetimes, where spacetime background can be described as a 3-brane embedded in an anti-de Sitter space of dimensions D ≥ 5 or as an intersection of higher dimensional branes with a four-dimensional brane intersection. Basica...
متن کاملOn D3-brane Potentials in Compactifications with Fluxes and Wrapped D-branes
We study the potential governing D3-brane motion in a warped throat region of a string compactification with internal fluxes and wrapped D-branes. If the Kähler moduli of the compact space are stabilized by nonperturbative effects, a D3-brane experiences a force due to its interaction with D-branes wrapping certain four-cycles. We compute this interaction, as a correction to the warped four-cyc...
متن کاملConical singularities regularized in warped six-dimensional flux compactification and their induced brane cosmology
We discuss the regularization of codimension-2 singularities in warped six-dimensional Einstein-Maxwell axisymmetric models by replacing them by codimension-1 branes of a ring form, situated around the axis of symmetry. Further we consider the case of one capped regularized conical brane of codimension one and study the cosmological evolution which is induced on it as it moves in between the kn...
متن کاملBouncing Brane Cosmologies from Warped String Compactifications
We study the cosmology induced on a brane probing a warped throat region in a CalabiYau compactification of type IIB string theory. For the case of a BPS D3-brane probing the Klebanov-Strassler warped deformed conifold, the cosmology described by a suitable brane observer is a bouncing, spatially flat Friedmann-Robertson-Walker universe with timevarying Newton’s constant, which passes smoothly ...
