Abstract

fetched live from OpenAlex

The latest results from the DEAP-3600 experiment will be presented. Located 2 km underground at SNOLAB in Sudbury, Canada, DEAP-3600 is looking to detect dark matter using 3.3 tonnes of liquid argon contained in a large ultralow-background acrylic cryostat that is instrumented with 255 photomultiplier tubes. Key to this experiment is the excellent demonstrated performance of pulse-shape discrimination against low-energy beta decays, as well as position reconstruction and other background rejection techniques against alpha decays and neutron scatters. The broad physics programme of DEAP-3600, with measurements and searches for new physics will be discussed, as well as the status of detector upgrades in progress.

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.
