{"arxiv_id":"0707.3342","title":"Automated calculations for multi-leg processes","abstract":"The search for signals of new physics at the forthcoming LHC experiments involves the analysis of final states characterised by a high number of hadronic jets or identified particles. Precise theoretical predictions for these processes require the computation of scattering amplitudes with a large number of external particles and beyond leading order in perturbation theory. The complexity of a calculation grows with the number of internal loops as well as with the number of external legs. Automatisation of at least next-to-leading order calculations for LHC processes is therefore a timely task. I will discuss various approaches.","primary_cat":"hep-ph","cross_cats":[],"submitted_at":"2007-07-23T09:26:46+00:00","latest_version":2,"source":"arxiv","source_label":"arXiv","source_url":null,"has_pdf":true,"has_source":false,"verdict":null,"confidence":null,"one_line_summary":null,"novelty_score":null,"correctness_risk":null,"formal_verification":null,"upvotes":0,"downvotes":0,"pith_score":0.0,"inbound_count":4,"_links":{"html":"https://pith.science/paper/0707.3342","verdict":"/api/v1/verdicts/0707.3342"}}
