{"arxiv_id":"hep-lat/0201019","title":"Chiral perturbation theory for the Wilson lattice action","abstract":"We extend chiral perturbation theory to include linear dependence on the lattice spacing $a$ for the Wilson action. The perturbation theory is written as a double expansion in the small quark mass $m_q$ and lattice spacing $a$. We present formulae for the mass and decay constant of a flavor-non-singlet meson in this scheme to order $a$ and $m_q^2$. The extension to the partially quenched theory is also described.","primary_cat":"hep-lat","cross_cats":["hep-ph","nucl-th"],"submitted_at":"2002-01-25T01:39:15+00:00","latest_version":1,"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":13,"_links":{"html":"https://pith.science/paper/hep-lat/0201019","verdict":"/api/v1/verdicts/hep-lat/0201019"}}
