Sensitivity for new light, long-lived flavor-changing scalar bosons at DUNE and NA64mu
Bibliographic record
Abstract
Neutrino-oscillations motivate the search for new beyond-the-Standard-Model particles that might manifest as light scalar bosons mediating lepton-flavor-changing (LFC) interactions. In a certain class of theories, the light scalar boson could be produced at accelerator neutrino beams, where a high-intensity, high-energy muon flux is expected. An example of such a facility is the Deep Underground Neutrino Experiment (DUNE) using the high-power proton beam at LBNF. If such a particle exists, it could be produced after the DUNE LBNF beam target. If it is long-lived, it could travel a few hundred meters, and it could be detected at the DUNE Liquid Argon Near Detector. In parallel, the existence of such a new LFC scalar boson can also be tested using the 160-GeV muon beam at the fixed target NA64mu experiment at CERN, in a complementary way. In this talk, light long-lived LFC boson signatures and projected sensitivities at DUNE and NA64mu will be presented.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
