Codimension-two branes in six-dimensional supergravity and the cosmological constant problem
Jérémie Vinet, James M. Cline
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 cosmol…
Generalised cosmology of codimension-two braneworlds
Jérémie Vinet
It has recently been argued that codimension-two braneworlds offer a promising line of attack on the cosmological constant problem, since in such models the Hubble rate is not dire…
Can codimension-two branes solve the cosmological constant problem?
Jérémie Vinet, James M. Cline
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 de…
A Comment on "Brans-Dicke Cosmology with a scalar field potential"
Jérémie Vinet
We show that a recent letter claiming to present exact cosmological solutions in Brans-Dicke theory actually uses a flawed set of equations as the starting point for their analysis…
Cosmology of codimension-two braneworlds
James M. Cline, Julie Descheneau, Massimo Giovannini +1
We present a comprehensive study of the cosmological solutions of 6D braneworld models with azimuthal symmetry in the extra dimensions, moduli stabilization by flux or a bulk scala…
Problems with Time-Varying Extra Dimensions or "Cardassian Expansion" as Alternatives to Dark Energy
James M. Cline, Jérémie Vinet
It has recently been proposed that the Universe might be accelerating as a consequence of extra dimensions with time varying size. We show that although these scenarios can lead to…
