Abstract
We study possible new physics (NP) effects on Bc→J/ψτν¯, which has been recently measured at LHCb as the ratio of RJ/ψ=B(Bc→J/ψτν¯)/B(Bc→J/ψμν¯). Combining it with the long-standing RD(⁎) measurements, in which the discrepancy with the prediction of the standard model is present, we find possible solutions to the anomaly by several NP types. Then, we see that adding the RJ/ψ measurement does not improve NP fit to data, but the NP scenarios still give better χ2 than the SM. We also investigate indirect NP constraints from the lifetime of Bc and NP predictions on the τ longitudinal polarization in B¯→D⁎τν¯.

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 it
