We present Poincare invariant domain wall (``3-brane'') solutions to some 5-dimensional effective theories which can arise naturally in string theory. In particular, we find theories where Poincare invariant solutions exist for arbitrary values of the brane tension, for certain restricted forms of the bulk interactions. We describe examples in string theory where it would be natural for the quantum corrections to the tension of the brane (arising from quantum fluctuations of modes with support on the brane) to maintain the required form of the action. In such cases, the Poincare invariant solutions persist in the presence of these quantum corrections to the brane tension, so that no 4d cosmological constant is generated by these modes.

The paper
Original abstract
We present Poincare invariant domain wall (``3-brane'') solutions to some 5-dimensional effective theories which can arise naturally in string theory. In particular, we find theories where Poincare invariant solutions exist for arbitrary values of the brane tension, for certain restricted forms of the bulk interactions. We describe examples in string theory where it would be natural for the quantum corrections to the tension of the brane (arising from quantum fluctuations of modes with support on the brane) to maintain the required form of the action. In such cases, the Poincare invariant solutions persist in the presence of these quantum corrections to the brane tension, so that no 4d cosmological constant is generated by these modes.

Warped models with singularities at a finite proper distance were first introduced[For an earlier analysis of models with exponential dilatonic brane potentials see Ref. [ref] .] to address the cosmological constant problem by self-tuning [ref] , although later it was shown that the cosmological constant fine-tuning could not be removed this way [ref] .

Notice that the self-tuning system discussed in [ref] can be recovered from ([ref]) by taking $λ= 4/3$ and $α=1$, which indeed corresponds to a bulk scalar field with standard kinetic term.

One of them is of course RS1 with GW mechanism, but there are more general models [For an earlier analysis of models with exponential (Liouville) dilatonic brane potentials see Ref.
