{"arxiv_id":"hep-lat/9407012","title":"An Exploratory Study of Nucleon-Nucleon Scattering Lengths in Lattice QCD","abstract":"An exploratory study is made of the nucleon-nucleon $s$-wave scattering lengths in quenched lattice QCD with the Wilson quark action. The $\\pi$-$N$ and $\\pi$-$\\pi$ scattering lengths are also calculated for comparison. The calculations are made with heavy quarks corresponding to $m_\\pi/m_\\rho\\approx 0.73-0.95$. The results show that the $N$-$N$ system has an attractive force in both spin-singlet and triplet channels, with their scattering lengths significantly larger than those for the $\\pi$-$N$ and $\\pi$-$\\pi$ cases, a trend which is qualitatively consistent with the experiment. Problems toward a more realistic calculation for light quarks are discussed.","primary_cat":"hep-lat","cross_cats":["nucl-th"],"submitted_at":"1994-07-19T06:01:54+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":8,"_links":{"html":"https://pith.science/paper/hep-lat/9407012","verdict":"/api/v1/verdicts/hep-lat/9407012"}}
