abstract
We obtain the general inflationary solutions for the slab of five-dimensional AdS spacetime where the fifth dimension is an orbifold $S^1/Z_2$ and two three-branes reside at its boundaries, of which the Randall-Sundrum model corresponds to the static limit. The investigation of the general solutions and their static limit reveals that the RS model recasts both the cosmological constant problem and the gauge hierarchy problem into the balancing problem of the bulk and the brane cosmological constants.

First Search for Kaluza-Klein Gravitons and Radion Using Planck Data
First Planck search for radion and KK-graviton bispectra finds no significant non-Gaussianity (max 1.8σ at m_KK ≈ 1.6H), while a warped 5D model can yield f_NL ~ 1–50.

Suppressing Extra-Dimensional Axion Isocurvature Dynamically
Radion dynamics in warped 5D models enhance the axion decay constant during inflation, satisfying CMB isocurvature bounds at higher Hubble scales while restoring the QCD window afterward.
