Gonzalez-Garcia, Michele Maltoni, Ivan Martinez-Soler, Jo\\~ao Paulo Pinheiro, Thomas Schwetz","year":2024,"venue":"hep-ph","abstract":"We present an updated global analysis of neutrino oscillation data as of September 2024. The parameters $\\theta_{12}$, $\\theta_{13}$, $\\Delta m^2_{21}$, and $|\\Delta m^2_{3\\ell}|$ ($\\ell = 1,2$) are well-determined with relative precision at $3\\sigma$ of about 13\\%, 8\\%, 15\\%, and 6\\%, respectively. The third mixing angle $\\theta_{23}$ still suffers from the octant ambiguity, with no clear indication of whether it is larger or smaller than $45^\\circ$. The determination of the leptonic CP phase $\\delta_{CP}$ depends on the neutrino mass ordering: for normal ordering the global fit is consistent with CP conservation within $1\\sigma$, whereas for inverted ordering CP-violating values of $\\delta_{CP}$ around $270^\\circ$ are favored against CP conservation at more than $3.6\\sigma$. While the present data has in principle $2.5$--$3\\sigma$ sensitivity to the neutrino mass ordering, there are different tendencies in the global data that reduce the discrimination power: T2K and NOvA appearance data individually favor normal ordering, but they are more consistent with each other for inverted ordering. Conversely, the joint determination of $|\\Delta m^2_{3\\ell}|$ from global disappearance data prefers normal ordering. Altogether, the global fit including long-baseline, reactor and IceCube atmospheric data results into an almost equally good fit for both orderings. Only when the $\\chi^2$ table for atmospheric neutrino data from Super-Kamiokande is added to our $\\chi^2$, the global fit prefers normal ordering with $\\Delta\\chi^2 = 6.1$. We provide also updated ranges and correlations for the effective parameters sensitive to the absolute neutrino mass from $\\beta$-decay, neutrinoless double-beta decay, and cosmology.","external_url":"https://arxiv.org/abs/2410.05380","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-05-25T07:45:29.487684+00:00","pith_arxiv_id":"2410.05380","created_at":"2026-05-09T06:20:40.837765+00:00","updated_at":"2026-05-25T07:45:29.487684+00:00","title_quality_ok":true,"display_title":"NuFit-6.0: Updated global analysis of three-flavor neutrino oscillations","render_title":"NuFit-6.0: Updated global analysis of three-flavor neutrino oscillations"},"hub":{"state":{"work_id":"b906c236-cb3d-4ee1-a23a-dd60cfeacff6","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":60,"external_cited_by_count":null,"distinct_field_count":5,"first_pith_cited_at":"2024-12-30T21:43:11+00:00","last_pith_cited_at":"2026-05-22T03:36:44+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":"2026-06-01T02:03:12.932770+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":19},{"context_role":"dataset","n":5},{"context_role":"method","n":2}],"polarity_counts":[{"context_polarity":"background","n":17},{"context_polarity":"use_dataset","n":5},{"context_polarity":"use_method","n":2},{"context_polarity":"support","n":1},{"context_polarity":"unclear","n":1}],"runs":{},"summary":{},"graph":{},"authors":[]}}
