Abstract

fetched live from OpenAlex

New heavy leptons with standard model gauge couplings have well-determined cross sections for pair production. A standard pattern of mass mixing implies that the most likely decays are ${\ensuremath{\tau}}^{\ensuremath{'}}\ensuremath{\rightarrow}W{\ensuremath{\nu}}^{\ensuremath{'}}$ and ${\ensuremath{\nu}}^{\ensuremath{'}}\ensuremath{\rightarrow}W\ensuremath{\tau}$. Interestingly there have been no direct searches for heavy leptons with these decays at the LHC. However comparison with several multilepton searches allows us to set new limits on the heavy lepton masses. Three observed excesses in the signal regions prevent us from setting stronger limits.

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.

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.
