Search for new physics in lepton plus photon plus X events with 929 pb(-1) of pp collisions at root s=1.96 TeV
Bibliographic record
Abstract
We present results of a search at CDF in 929 +/- 56 pb(-1) of p (p) over bar collisions at 1.96 TeV for the anomalous production of events containing a high-transverse momentum charged lepton (l, either e or mu) and photon (gamma), accompanied by missing transverse energy (E-T), and/or additional leptons and photons, and jets (X). We use the same selection criteria as in a previous CDF Run I search, but with an order-magnitude larger data set, a higher p (p) over bar collision energy, and the CDF II detector. We find 163 l gamma E-T + X events, compared to an expectation of 150.6 +/- 13.0 events. We observe 74 ll gamma + X events, compared to an expectation of 65.1 +/- 7.7 events. We find no events similar to the Run I ee gamma gamma E-T event.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
