{"arxiv_id":"hep-lat/0509065","title":"Magnetic polarizability of hadrons from lattice QCD in the background field method","abstract":"We present a calculation of hadron magnetic polarizability using the techniques of lattice QCD. This is carried out by introducing a uniform external magnetic field on the lattice and measuring the quadratic part of a hadron's mass shift. The calculation is performed on a $24^4$ lattice with standard Wilson actions at beta=6.0 (spacing $a=0.1$ fm) and pion mass down to about 500 MeV. Results are obtained for 30 particles covering the entire baryon octet ($n$, $p$, $\\Sigma^0$, $\\Sigma^-$, $\\Sigma^+$, $\\Xi^-$, $\\Xi^0$, $\\Lambda$) and decuplet ($\\Delta^0$, $\\Delta^-$, $\\Delta^+$, $\\Delta^{++}$, $\\Sigma^{*0}$, $\\Sigma^{*-}$, $\\Sigma^{*+}$, $\\Xi^{*0}$, $\\Xi^{*-}$, $\\Omega^-$), plus selected mesons ($\\pi^0$, $\\pi^+$, $\\pi^-$, $K^0$, $K^+$, ${K}^-$, $\\rho^0$, $\\rho^+$, $\\rho^-$, $K^{*0}$, $K^{*+}$, $K^{*-}$). The results are compared with available values from experiments and other theoretical calculations.","primary_cat":"hep-lat","cross_cats":["hep-ex","hep-ph","nucl-ex","nucl-th"],"submitted_at":"2005-09-21T01:32:16+00:00","latest_version":1,"source":"arxiv","source_label":"arXiv","source_url":null,"has_pdf":true,"has_source":false,"verdict":"CONDITIONAL","confidence":"HIGH","one_line_summary":"First lattice QCD survey of magnetic polarizabilities for 30 hadrons, extracted from the quadratic mass shift in an external magnetic field.","novelty_score":6.0,"correctness_risk":"medium","formal_verification":"none","upvotes":0,"downvotes":0,"pith_score":0.0,"inbound_count":12,"_links":{"html":"https://pith.science/paper/hep-lat/0509065","verdict":"/api/v1/verdicts/hep-lat/0509065"}}
