Moduli stabilization in the heterotic/IIB discretuum
Bibliographic record
Abstract
Abstract We consider supersymmetric compactifications of type IIB and the weakly coupled heterotic string with G resp. H‐flux and gaugino condensation in a hidden sector included. We point out that proper inclusion of the non‐perturbative effects changes the Hodge structure of the allowed fluxes in type IIB significantly. In the heterotic theory it is known that, in contrast to the potential read off from dimensional reduction, the effective four‐dimensional description demands for consistency a non‐vanishing H2,1 component if a H3,0 component is already present balancing the condensate. The H2,1 component causes a non‐Kählerness of the underlying geometry whose moduli space is, however, not well‐understood. We show that the occurrence of H2,1 might actually be avoided by using a KKLT‐like two‐step procedure for moduli stabilization. Independently of the H2,1 issue one‐loop corrections to the gauge couplings were argued to cause a not well‐controlled strong coupling transition. This problem can be avoided as well when the effects of world‐sheet instantons are included. They will also stabilize the Kähler modulus what was accomplished by H2,1 before.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
