Abstract
n the current cosmological paradigm, Dark Matter (DM) constitutes a large portion (about 27 %) of the mass and energy content of the Universe. One DM candidate, the Weakly Interacting Massive Particle (WIMP), can potentially have a mass in the range from 50 GeV to greater than 10 TeV. Self-annihilation and/or decay of WIMPs may produce various secondary particles, producing very-high-energy gamma rays (VHE; above 100 GeV). The signature of the WIMP signal has been searched with state-of-art observatories, but it has not been successful. This lack of success proposes a new parameter range, ultra-heavy DM (UHDM). In this talk, I will summarize the status of the WIMP search, focusing on the Very Energetic Radiation Imaging Telescope Array System (VERITAS) result, and explore the feasibility of detecting the annihilation signature for UHDM with current and future VHE gamma-ray observatories. Finally, I will present the result of the UHDM search with VERITAS.

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.
