Computations were performed on the SFB/TR55 QPACE supercomputers, the BlueGene/P (JuGene) and the Nehalem Cluster (JuRoPA) of the Julich Supercomputer Center, the IBM BlueGene/L at the EPCC (Edinburgh), the SGI Altix ICE machines at HLRN (Berlin/Hannover), and Regensburg's Athene HPC cluster. The CHROMA software suite [33] was used and gauge configurations were generated with the BQCD code [34]. 000019010 520__ $$aWe compute the strangeness and light-quark contributions Delta s, Delta u, and Delta d to the proton spin in n(f) = 2 lattice QCD at a pion mass of about 285 MeV and at a lattice spacing a approximate to 0.073 fm, using the nonperturbatively improved Sheikholeslami-Wohlert Wilson action. We carry out the renormalization of these matrix elements, which involves mixing between contributions from different quark flavors. Our main result is the small negative value Delta s((MS) over bar)(root 7.4 GeV) = -0.020(10)(4) of the strangeness contribution to the nucleon spin. The second error is an estimate of the uncertainty, due to the missing extrapolation to the physical point. 000019010 536__ $$0G:(DE-Juel1)FUEK411$$2G:(DE-HGF)$$aScientific Computing (FUEK411)$$cFUEK411$$x0 000019010 536__ $$0G:(DE-HGF)POF2-411$$a411 - Computational Science and Mathematical Methods (POF2-411)$$cPOF2-411$$fPOF II$$x1 000019010 536__ $$0G:(EU-Grant)238353$$aSTRONGNET - Strong Interaction Supercomputing Training Network (238353)$$c238353$$fFP7-PEOPLE-ITN-2008$$x2 000019010 588__ $$aDataset connected to Web of Science 000019010 650_7 $$2WoSType$$aJ 000019010 7001_ $$0P:(DE-HGF)0$$aCollins, S.$$b1 000019010 7001_ $$0P:(DE-HGF)0$$aGöckeler, M.$$b2 000019010 7001_ $$0P:(DE-HGF)0$$aHorsley, R.$$b3 000019010 7001_ $$0P:(DE-HGF)0$$aNakamura, Y.$$b4 000019010 7001_ $$0P:(DE-Juel1)145828$$aNobile, A.$$b5$$uFZJ 000019010 7001_ $$0P:(DE-Juel1)144441$$aPleiter, D.$$b6$$uFZJ 000019010 7001_ $$0P:(DE-HGF)0$$aRakow, P.E.L.$$b7 000019010 7001_ $$0P:(DE-HGF)0$$aSchäfer, A.$$b8 000019010 7001_ $$0P:(DE-HGF)0$$aSchierholz, G.$$b9 000019010 7001_ $$0P:(DE-HGF)0$$aZanotti, J.M.$$b10 000019010 773__ $$0PERI:(DE-600)1472655-5$$a10.1103/PhysRevLett.108.222001$$gVol. 108, p. 222001$$p222001$$q108<222001$$tPhysical review letters$$v108$$x0031-9007$$y2012 000019010 8567_ $$uhttp://dx.doi.org/10.1103/PhysRevLett.108.222001 000019010 8564_ $$uhttps://juser.fz-juelich.de/record/19010/files/FZJ-19010.pdf$$yOpenAccess$$zPublished final document. 000019010 8564_ $$uhttps://juser.fz-juelich.de/record/19010/files/FZJ-19010.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 000019010 8564_ $$uhttps://juser.fz-juelich.de/record/19010/files/FZJ-19010.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000019010 8564_ $$uhttps://juser.fz-juelich.de/record/19010/files/FZJ-19010.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000019010 909CO $$ooai:juser.fz-juelich.de:19010$$pdnbdelivery$$pec_fundedresources$$pVDB$$pdriver$$popen_access$$popenaire 000019010 915__ $$0LIC:(DE-HGF)APS-112012$$2HGFVOC$$aAmerican Physical Society Transfer of Copyright Agreement 000019010 915__ $$0StatID:(DE-HGF)0010$$2StatID$$aJCR/ISI refereed 000019010 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR 000019010 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000019010 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000019010 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000019010 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bThomson Reuters Master Journal List 000019010 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000019010 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000019010 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database 000019010 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz 000019010 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000019010 915__ $$0StatID:(DE-HGF)1020$$2StatID$$aDBCoverage$$bCurrent Contents - Social and Behavioral Sciences 000019010 9141_ $$y2012 000019010 9132_ $$0G:(DE-HGF)POF3-511$$1G:(DE-HGF)POF3-510$$2G:(DE-HGF)POF3-500$$aDE-HGF$$bKey Technologies$$lSupercomputing & Big Data$$vComputational Science and Mathematical Methods$$x0 000019010 9131_ $$0G:(DE-HGF)POF2-411$$1G:(DE-HGF)POF2-410$$2G:(DE-HGF)POF2-400$$3G:(DE-HGF)POF2$$4G:(DE-HGF)POF$$aDE-HGF$$bSchlüsseltechnologien$$lSupercomputing$$vComputational Science and Mathematical Methods$$x4 000019010 9201_ $$0I:(DE-Juel1)JSC-20090406$$gJSC$$kJSC$$lJülich Supercomputing Centre$$x0 000019010 970__ $$aVDB:(DE-Juel1)133729 000019010 980__ $$aVDB 000019010 980__ $$aConvertedRecord 000019010 980__ $$ajournal 000019010 980__ $$aI:(DE-Juel1)JSC-20090406 000019010 980__ $$aUNRESTRICTED 000019010 980__ $$aFullTexts 000019010 9801_ $$aFullTexts
