Inert doublet dark matter with strong electroweak phase transition
Bibliographic record
Abstract
We reconsider the strength of the electroweak phase transition in the inert doublet dark matter model, using a quantitatively accurate form for the one-loop finite temperature effective potential, taking into account relevant particle physics and dark matter constraints, focusing on a standard model Higgs mass near 126 GeV, and doing a full scan of the space of otherwise unconstrained couplings. We find that there is a significant (although fine-tuned) space of parameters for achieving an electroweak phase transition sufficiently strong for baryogenesis while satisfying the XENON100 constraints from direct detection and not exceeding the correct thermal relic density. We predict that the dark matter mass should be in the range 60--67 GeV, and we discuss possible LHC signatures of the charged and $CP$-odd Higgs bosons, including an $\ensuremath{\sim}10%$ enhancement of the $h\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\gamma}$ branching ratio.

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.
