Abstract

fetched live from OpenAlex

We report an updated measurement of the $CP$-violating phase, ${\ensuremath{\phi}}_{s}^{J/\ensuremath{\psi}\ensuremath{\phi}}$, and the decay-width difference for the two mass eigenstates, $\ensuremath{\Delta}{\ensuremath{\Gamma}}_{s}$, from the flavor-tagged decay ${B}_{s}^{0}\ensuremath{\rightarrow}J/\ensuremath{\psi}\ensuremath{\phi}$. The data sample corresponds to an integrated luminosity of $8.0\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ accumulated with the D0 detector using $p\overline{p}$ collisions at $\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$ produced at the Fermilab Tevatron collider. The 68% Bayesian credibility intervals, including systematic uncertainties, are $\ensuremath{\Delta}{\ensuremath{\Gamma}}_{s}={0.163}_{\ensuremath{-}0.064}^{+0.065}\text{ }\text{ }{\mathrm{ps}}^{\ensuremath{-}1}$ and ${\ensuremath{\phi}}_{s}^{J/\ensuremath{\psi}\ensuremath{\phi}}=\ensuremath{-}{0.55}_{\ensuremath{-}0.36}^{+0.38}$. The $p$-value for the Standard Model point is 29.8%.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction

Teacher imitation

Not 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.
