abstract

We describe how the D-brane spectra of the various ten-dimensional string theories can be related to general properties of the open-closed duality, encoded in the $S$ and $P$ matrices of the conformal field theory. We also complete the classification and the description of non-BPS branes in these string theories, elucidating their non-Abelian structures and the nature of the corresponding super-Higgs mechanisms. We find that the type 0 theories and their orientifolds have two types of uncharged branes, distinguished by their couplings to the closed string tachyon. We also find that the 0A orientifold has the unusual feature of having charged and uncharged branes with identical world-volume dimensions. We conclude with some comments on fractional branes, elucidating their role in connection with the boundary states of $D_{odd}$ SU(2) WZW models.

    hep-th 2026-03 unverdicted novelty 7.0 of 10

    Hořava-Witten theory on S¹∨S¹ is dual to a type 0B orientifold with SO(16)^4 gauge group, explaining gauge group doubling via the geometry's junction and revealing two variants from E8 wall orientations.

  2. Linear and nonlinear supersymmetry in field and string theory

    hep-th 2025-06 conditional novelty 7.0 of 10

    Consistency criteria for constrained superfields, a gravitino energy and particle-production puzzle, the unique leading-order massive spin-2 to supergravity coupling, and a twisted Scherk-Schwarz orientifold with full...

  3. Non-supersymmetric dualities beyond the gauge algebra

    hep-th 2026-06 unverdicted novelty 6.0 of 10

    Verification of Blum-Dienes and Bergman-Gaberdiel dualities shows agreement in gauge group global forms from orientifold brane states and internal lattices, with one subtle projection exception.

  4. 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.

  5. Anomaly Inflow and Gauge Group Topology in the 10d Sugimoto String Theory

    hep-th 2024-12 conditional novelty 6.0 of 10

    Anomaly inflow on Sugimoto model branes supports the conclusion that the 10d gauge group is Sp(16)/Z2, and the same inflow matching rules out most alternative chiral spectra.

  6. Aspects of strings without spacetime supersymmetry

    hep-th 2025-09 unverdicted novelty 2.0 of 10

    A survey of tachyons and tadpoles in non-supersymmetric closed and orientifold strings, including ten-dimensional models and landscape attempts.
