Abstract
We present a search for charged Higgs bosons in top quark decays. We analyze the e + jets , μ + jets , ee , eμ , μμ , τe and τμ final states from top quark pair production events, using data from about 1 fb −1 of integrated luminosity recorded by the DØ experiment at the Fermilab Tevatron Collider. We consider different scenarios of possible charged Higgs boson decays, one where the charged Higgs boson decays purely hadronically into a charm and a strange quark, another where it decays into a τ lepton and a τ neutrino and a third one where both decays appear. We extract limits on the branching ratio B ( t → H + b ) for all these models. We use two methods, one where the t t ¯ production cross section is fixed, and one where the cross section is fitted simultaneously with B ( t → H + b ) . Based on the extracted limits, we exclude regions in the charged Higgs boson mass and tan β parameter space for different scenarios of the minimal supersymmetric standard model.

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
