A blind analysis is carried out on the entire data set. The data processing is improved compared to previous work, unifying the low-level signal reconstruction in a wide energy range up to 120 keV. With a total exposure of 1.54 tonne$\\cdot$year, no significant excess of nuclear recoil events is found. The lowest 90% confidence level exclusion on the spin-independent cross section is $1.6 \\times 10^{-47}\\,\\mathrm{cm}^2$ at a dark matter mass of 40 GeV$/c^2$. Our results represent the most stringent constraint for a dark matter mass above 100 GeV$/c^2$.","external_url":"https://arxiv.org/abs/2408.00664","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-07-10T13:27:05.854218+00:00","pith_arxiv_id":"2408.00664","created_at":"2026-05-10T06:01:13.503799+00:00","updated_at":"2026-07-10T13:27:05.854218+00:00","title_quality_ok":true,"display_title":"Dark Matter Search Results from 1.54 Tonne·Year Exposure of PandaX-4T","render_title":"Dark Matter Search Results from 1.54 Tonne·Year Exposure of PandaX-4T"},"hub":{"state":{"work_id":"b2d7de9e-fee6-43b7-803e-7b139e7b7be6","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":22,"external_cited_by_count":null,"distinct_field_count":4,"first_pith_cited_at":"2024-10-22T14:07:18+00:00","last_pith_cited_at":"2026-07-09T03:32:31+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":"2026-08-21T11:29:48.954538+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":3},{"context_role":"baseline","n":2}],"polarity_counts":[{"context_polarity":"background","n":3},{"context_polarity":"baseline","n":2}],"runs":{},"summary":{},"graph":{},"authors":[]}}
