We discuss some issues arising in studying (linearized) gravity on non-BPS higher codimension branes in an infinite-volume bulk. In particular, such backgrounds are badly singular for codimension-3 and higher delta-function-like branes with non-zero tension. As we discuss in this note, non-trivial issues arise in smoothing out such singularities. Thus, adding higher curvature terms might be necessary in this context. 

Smooth tensionful higher-codimensional brane worlds with bulk and brane form fields

Completely regular tensionful codimension-n brane world solutions are discussed, where the core of the brane is chosen to be a thin codimension-(n − 1) shell in an infinite volume flat bulk, and an

The Effective field theory of codimension-two branes

Distributional sources of matter on codimension-two and higher branes are only well-defined as regularized objects. Nevertheless, intuition from effective field theory suggests that the low-energy

A quasi-thick codimension 2 braneworld

We study a codimension 2 braneworld in the Einstein–Gauss–Bonnet gravity. We carefully examine the structure of possible singularities in the system which characterize the braneworld through matching

Toward Solving the Cosmological Constant Problem

We discuss the cosmological constant problem in the context of higher codimension brane world scenarios with infinite-volume extra dimensions. In particular, by adding higher curvature terms in the

Codimension-two branes in six-dimensional supergravity and the cosmological constant problem

We investigate in detail recent suggestions that codimension-two braneworlds in six-dimensional supergravity might circumvent Weinberg's no-go theorem for self-tuning of the cosmological constant.

A NOVEL APPROACH TO THE COSMOLOGICAL CONSTANT PROBLEM

We propose a novel infinite-volume brane world scenario where we live on a noninflating spherical 3-brane, whose radius is somewhat larger than the present Hubble size, embedded in higher dimensional

Gravitational waves in a codimension two braneworld

We consider the propagation of gravitational waves in six dimensions induced by sources living on 3-branes in the context of a recent exact solution (Mukohyama et al 2005 J. Cosmol. Astropart. Phys.

Blown-up p-branes and the cosmological constant

We consider a blown-up 3-brane, with the resulting geometry R(3,1) × S(N − 1), in an infinite-volume bulk with N > 2 extra dimensions. The action on the brane includes both an Einstein term and a

Blown-up p-branes and the cosmological constant

We consider a blown-up 3-brane, with the resulting geometry R(3,1) × S(N − 1), in an infinite-volume bulk with N > 2 extra dimensions. The action on the brane includes both an Einstein term and a

Can codimension-two branes solve the cosmological constant problem?

It has been suggested that codimension-two braneworlds might naturally explain the vanishing of the 4D effective cosmological constant, due to the automatic relation between the deficit angle and the
