Preprint typeset in JHEP style- HYPER VERSION McGill-04/24. UV Sensitivity in Supersymmetric Large Extra Dimensions: The Ricci-flat Case
Bibliographic record
Abstract
Abstract: We examine the ultraviolet (UV)-sensitive part of the one-loop Casimir energy which is induced when various higher-dimensional supergravities are compactified to 4D on extra dimensions which are Ricci flat, but otherwise arbitrary. We identify the leading dependence on the mass of very massive higher-dimensional modes, as well as the UV divergent part of the contributions of modes which are massless in the higher-dimensional sense (but which consist of a KK tower of massive modes from the 4D perspective), and show how these are constrained by higher-dimensional general covariance. Some of the implications of co-dimension 2 branes are computed in the limit where their tension is small compared with the extra-dimensional Planck scale (but not small compared with the observed dark energy). Our results support the interpretation of supersymmetric large extra dimensions (SLED) in 6 dimensions as a potential solution to the cosmological constant problem (but do not yet completely clinch the case). This article is dedicated to Bryce DeWitt — a pioneer in the heat-kernel techniques

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
