The corresponding data have been used for axion and light Higgs particle searches in Refs. \\cite{Blumlein:1990ay,Blumlein:1991xh} before. More recently, limits on dark gauge forces have been derived from this data set, considering a dark photon production from $\\pi^0$-decay \\cite{Blumlein:2011mv}. Here we determine extended mass and coupling exclusion bounds for dark gauge bosons ranging to masses $m_{\\gamma'}$ of 624 MeV at admixture parameters $\\varepsilon \\simeq 10^{-6}$ considering high-energy Bremsstrahlung of the $U$-boson off the initial proton beam and different detection mechanisms.","external_url":"https://arxiv.org/abs/1311.3870","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-05-22T09:34:47.338132+00:00","pith_arxiv_id":"1311.3870","created_at":"2026-05-10T01:56:07.426834+00:00","updated_at":"2026-06-05T21:23:00.469572+00:00","title_quality_ok":true,"display_title":"New Exclusion Limits on Dark Gauge Forces from Proton Bremsstrahlung in Beam-Dump Data","render_title":"New Exclusion Limits on Dark Gauge Forces from Proton Bremsstrahlung in Beam-Dump Data"},"hub":{"state":{"work_id":"961d43ab-0d07-436a-90bc-55686daa38a8","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":10,"external_cited_by_count":null,"distinct_field_count":2,"first_pith_cited_at":"2020-05-04T14:31:03+00:00","last_pith_cited_at":"2026-05-20T18:00:01+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":"2026-06-26T05:14:32.842967+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":2},{"context_role":"baseline","n":1},{"context_role":"method","n":1}],"polarity_counts":[{"context_polarity":"background","n":2},{"context_polarity":"baseline","n":1},{"context_polarity":"use_method","n":1}],"runs":{},"summary":{},"graph":{},"authors":[]}}
