The main takeaway is that the 2025 Fermilab result has sharpened the muon g-2 test, while hadronic vacuum polarization remains the dominant uncertainty and no confirmed new-physics signal is established in the sources reviewed.","version":1,"published_at":"2026-10-30","updated_at":"2026-10-30","stats":{"words":4477,"citations":60,"claims":30,"timeline":16,"benchmarks":16,"open_problems":6,"key_papers":15,"glossary":14},"verification":{"status":"verified","method":"independent AI fact-check against cited sources (evidence pack + web checks); automated citation resolution","claims_checked":30,"issues_fixed":20,"verified_at":"2026-10-30"},"ai_assisted":true,"price":{"usd":"0.20","protocol":"x402","network":"eip155:84532","asset":"USDC"},"url":"https://space-kitty.com/dossiers/particle-physics-bsm","preview_url":"https://space-kitty.com/api/v1/dossiers/particle-physics-bsm/preview","purchase_url":"https://space-kitty.com/api/v1/dossiers/particle-physics-bsm"},"top_papers":[{"id":"arxiv:2104.03281","kind":"article","title":"Measurement of the Positive Muon Anomalous Magnetic Moment to 0.46 ppm","authors":["B.
