Witten long ago pointed out that the simplest Kaluza-Klein theory, without supersymmetry, is subject to a catastrophic instability. There are a variety of string theories which are potentially subject to these instabilities. Here we explore a number of questions: how generic are these instabilities? what happens when a potential is generated on the moduli space? in the presence of supersymmetry breaking, is there still a distinction between supersymmetric and non-supersymmetric states?

Discussion (0). Continue with ORCID to comment.

  1. A more effective QCD string at colliders: Decay of excited strings and the worldsheet axion

    hep-ph 2026-06 unverdicted novelty 7.0 of 10

    Excitations of the worldsheet axion in an effective QCD string theory produce a phase-dependent effective tension that exponentially modifies the rate of string breaking via quark pair nucleation.

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

    hep-th 2026-05 unverdicted novelty 6.0 of 10

    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.

  3. An Exploration of Vacuum-Decay Valleys

    hep-th 2025-06 conditional novelty 6.0 of 10

    Single-field potentials can exhibit 2n+1 distinct vacuum-decay bounces, including antibounces that standard overshoot/undershoot algorithms miss, connected by families of pseudo-bounces.

  4. Morse-Bott inequalities, Topology Change and Cobordisms to Nothing

    hep-th 2024-10 unverdicted novelty 6.0 of 10

    Morse-Bott inequalities yield homology bounds and topology-change counts for generic cobordisms to nothing in string theory compactifications.
