Codimension-2 branes: Episode 2:
The cosmological
constant strikes back
Jérémie Vinet

Codimension-2 braneworlds have recently come under much scrutiny as a
possible way of confronting and perhaps resolving the cosmological constant
problem.
In this talk, I will review the reasons that have led people to believe that
codimension-2 braneworlds hold such promise, and I will present the result of
ongoing work which tries to clarify whether the apparent automatic
cancellation of the cosmological constant in these models represents
self-tuning or fine-tuning.
