We investigate the asymptotic behavior of Kaluza-Klein (KK) towers in warped compactifications to Minkowski space. Focusing on the overall decompactification limit, we derive the scaling of KK masses at large KK momentum for scalar fluctuations in lower-dimensional Planck units. In codimension-one warped backgrounds sourced by a higher-dimensional exponential potential, we solve explicitly for the internal profiles and obtain a closed expression for the exponential mass decay rate $\lambda_{\rm KK}$ of the tower in terms of the moduli space distance. We find that warping reduces $\lambda_{\rm KK}$ relative to the unwarped case, in such a way that sufficiently strong warping could in principle violate the Sharpened Distance Conjecture bound. Remarkably, this sharpened bound is still satisfied precisely when the higher-dimensional potential obeys the condition forbidding asymptotic accelerated expansion, establishing a direct link between the Sharpened Distance Conjecture and the Strong de Sitter condition in one higher dimension. We also argue that for higher-codimension warped backgrounds the asymptotic KK scaling remains unmodified.

  1. Sharpened Dynamical Cobordism

    hep-th 2026-05 unverdicted novelty 7.0

    Sharpened Dynamical Cobordism ties the allowed range of critical exponent δ to theory structure ξ, flagging obstructions from non-trivial cobordism charges that require new degrees of freedom.

  2. String theory in the infrared

    hep-th 2026-04 unverdicted novelty 4.0

    Worldsheet analysis shows that string theory effective theories obey UV/IR scaling relations between Wilson coefficients and vacuum energy, producing holographic bounds invisible to standard effective field theory.
