{"arxiv_id":"hep-lat/0504022","title":"Chiral and Continuum Extrapolation of Partially-Quenched Lattice Results","abstract":"The vector meson mass is extracted from a large sample of partially quenched, two-flavor lattice QCD simulations. For the first time, discretisation, finite-volume and partial quenching artefacts are treated in a unified framework which is consistent with the low-energy behaviour of QCD. This analysis incorporates the leading infrared behaviour dictated by chiral effective field theory. As the two-pion decay channel cannot be described by a low-energy expansion alone, a highly-constrained model for the decay channel of the rho-meson is introduced. The latter is essential for extrapolating lattice results from the quark-mass regime where the rho is observed to be a physical bound state.","primary_cat":"hep-lat","cross_cats":[],"submitted_at":"2005-04-28T14:42:02+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,"inbound_count":5,"_links":{"html":"https://pith.science/paper/hep-lat/0504022","verdict":"/api/v1/verdicts/hep-lat/0504022"}}
