<i>R</i><sup>2</sup>log<i>R</i>quantum corrections and the inflationary observables
Bibliographic record
Abstract
We study a model of inflation with terms quadratic and logarithmic in the Ricci scalar, where the gravitational action is f ( R )= R +α R 2 +β R 2 ln R . These terms are expected to arise from one loop corrections involving matter fields in curved space-time. The spectral index n s and the tensor to scalar ratio yield 4 × 10 -4 ≲ r ≲0.03 and 0.94≲ n s ≲ 0.99. i.e. r is an order of magnitude bigger or smaller than the original Starobinsky model which predicted r ∼ 10 -3 . Further enhancement of r gives a scale invariant n s ∼ 1 or higher. Other inflationary observables are d n s / d ln k ≳ -5.2 × 10 -4 , μ ≲ 2.1 × 10 -8 , y ≲ 2.6 × 10 -9 . Despite the enhancement in r , if the recent BICEP2 measurement stands, this model is disfavoured.

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.
