Why this work is in the frame

A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

fundA Canadian funder is recorded on the work.
no affNo Canadian affiliation: this work is invisible to an affiliation-only frame.
No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

In a sample of 467×106 BB̄ pairs collected with the BABAR detector at the PEP-II collider at SLAC we have observed the decay B̄0→Λc+p̄π0 and measured the branching fraction to be (1.94±0.17±0.14±0.50)×10 - 4, where the uncertainties are statistical, systematic, and the uncertainty on the Λc+→pK - π + branching fraction, respectively. We determine an upper limit of 1.5×10 - 6 at 90% C.L. for the product branching fraction B(B̄0→Σc+(2455)p̄) ×B(Λc+→pK - π + ). Furthermore, we observe an enhancement at the threshold of the invariant mass of the baryon-antibaryon pair. © 2010 The American Physical Society.

Full frame distilled prediction

Teacher imitation

Not 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.
