We reduce uncertainties compared to our earlier computation arXiv:2002.12347 by a factor of 1.6. We perform simulations on finer lattices allowing for an even more accurate continuum extrapolation. We also include a small, long-distance contribution obtained using input from experiments in a low-energy regime where they all agree. Combined with other standard model contributions our result, $a_\\mu^{LO-HVP}=715.1(2.5)(2.3)[3.4] \\times 10^{-10}$, leads to a prediction that differs from the recent measurement of $a_\\mu$ by only 0.5 standard deviations. This provides a remarkable validation of the standard model to 11 digits.","external_url":"https://arxiv.org/abs/2407.10913","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-05-18T17:21:39.694105+00:00","pith_arxiv_id":"2407.10913","created_at":"2026-05-10T23:00:49.085920+00:00","updated_at":"2026-05-18T17:21:39.694105+00:00","title_quality_ok":true,"display_title":"Hybrid calculation of hadronic vacuum polarization in muon g-2 to 0.48\\%","render_title":"Hybrid calculation of hadronic vacuum polarization in muon g-2 to 0.48\\%"},"hub":{"state":{"work_id":"ac831006-ceea-4710-9beb-e56a68a83e76","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":13,"external_cited_by_count":null,"distinct_field_count":2,"first_pith_cited_at":"2024-11-06T21:21:37+00:00","last_pith_cited_at":"2026-05-12T14:45:42+00:00","author_build_status":"not_needed","summary_status":"needed","contexts_status":"needed","graph_status":"needed","ask_index_status":"not_needed","reader_status":"not_needed","recognition_status":"not_needed","updated_at":"2026-05-18T23:21:14.610865+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":4},{"context_role":"baseline","n":1}],"polarity_counts":[{"context_polarity":"background","n":4},{"context_polarity":"baseline","n":1}],"runs":{},"summary":{},"graph":{},"authors":[]}}
