One-loop amplitudes for massless supersymmetric gauge theories fall into this class; in addition, many non-supersymmetric amplitudes can be rearranged to take advantage of the result. As applications, we construct the one-loop amplitudes for $n$-gluon scattering in $N=1$ supersymmetric theories with the helicity configuration of the Parke-Taylor tree amplitudes, and for six-gluon scattering in $N=4$ super-Yang-Mills theory for all helicity configurations.","external_url":"https://arxiv.org/abs/hep-ph/9409265","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-07-03T07:27:44.688246+00:00","pith_arxiv_id":"hep-ph/9409265","created_at":"2026-05-11T16:01:17.975504+00:00","updated_at":"2026-07-03T07:27:44.688246+00:00","title_quality_ok":true,"display_title":"Fusing Gauge Theory Tree Amplitudes Into Loop Amplitudes","render_title":"Fusing Gauge Theory Tree Amplitudes Into Loop Amplitudes"},"hub":{"state":{"work_id":"0196fc6b-f6cf-42c2-b644-a0d9095730a5","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":18,"external_cited_by_count":null,"distinct_field_count":2,"first_pith_cited_at":"2019-06-27T18:24:17+00:00","last_pith_cited_at":"2026-06-26T15:38:20+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":"2026-07-03T21:05:40.994018+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":4}],"polarity_counts":[{"context_polarity":"background","n":4}],"runs":{},"summary":{},"graph":{},"authors":[]}}
