In the effective field theory of quantum gravitation coupled to N_s scalars, N_f fermions, and N_V vectors, tree unitarity is violated at an energy squared of E_{CM}^2 = 20(G_N N)^{-1}, where N = {2/3}N_s + N_f + 4N_V and G_N is Newton's constant. This is related to radiative corrections proportional to G_N N E^2 (where E is the typical energy), due to loops of such particles. New physics must enter before E_{CM}=5.6 x 10^{18} GeV in the standard model, and 4.6 x 10^{18} GeV in the minimal supersymmetric standard model.

  1. Alice in Warpland: KK modes, Warped Compactifications and the Swampland

    hep-th 2026-03 unverdicted novelty 7.0

    In codimension-one warped compactifications with exponential potentials, the KK mass decay rate λ_KK is reduced by warping but still satisfies the Sharpened Distance Conjecture precisely when the higher-dimensional po...

  2. Kaluza-Klein tower thresholds and scheme dependence of the species scale

    hep-th 2026-07 accept novelty 6.5

    Leading KK-tower local corrections to four-derivative gravity are regulator-dependent EFT matching data, while log N terms are universal within proper-time cutoffs, so species-scale definitions match only parametrically.

  3. Bordisms between 9d type IIB supergravities and commutator widths of duality groups

    hep-th 2026-05 unverdicted novelty 6.0

    Proposes a refinement of the Swampland Cobordism Conjecture for Ω1(BG) with duality bundle G, where diverging commutator width of G requires infinitely many duality defects to realize monodromies via gravitational solitons.

  4. Bordisms between 9d type IIB supergravities and commutator widths of duality groups

    hep-th 2026-05 unverdicted novelty 6.0

    Proposes a refinement of the Swampland Cobordism Conjecture for duality groups, arguing that diverging commutator widths necessitate infinitely many duality defects to realize monodromies in 9d supergravity bordisms.

  5. Conventional and Unitarity-Conserving Peccei-Quinn Inflation Models and ACT

    hep-ph 2026-03 unverdicted novelty 4.0

    Unitarity-conserving Peccei-Quinn inflation agrees with ACT data within 1 sigma and allows axion decay constants up to 6.4e13 GeV without post-inflation symmetry restoration, unlike the conventional model.
