Abstract: The Randall-Sundrum model of warped geometry in a five-dimensional scenario,aimed at explaining the hierarchy between the Planck and electroweak scales, isintrinsically unstable in its minimal form due to negative tension of thevisible brane. A proposed solution to the problem yields a negativecosmological constant in four dimensions. We show that this wrong-signcosmological constant is restricted to small values, therefore requiring lesscancellation from hitherto unknown physics, if bulk neutrinos are postulated toexplain the observed neutrino mass pattern. Thus neutrino masses, a stableTev-brane configuration and new physics in the context of the cosmologicalconstant get rather suggestively connected by the same thread.
