The second order perturbative expansion of the plaquette expectation value is employed to determine αS at a scale set by the 2S−1S and 1P−1S level splittings. The latter are computed in NRQCD in a dynamical gauge field background with two degenerate flavors of Wilson quarks at intermediate masses and extrapolated to the chiral limit. Combining the Nf=2 result with the quenched result at equal lattice spacing we extrapolate to the physical number of light flavors to find a value of α(5)¯MS(mZ)=0.1118(17). The error quoted covers both statistical and systematic uncertainties in the scale determination. An additional 5% uncertainty comes from the choice of the underlying sea quark formulation and from truncation errors in perturbative expansions. 000860319 542__ $$2Crossref$$i1999-09-03$$uhttp://link.aps.org/licenses/aps-default-license 000860319 588__ $$aDataset connected to CrossRef 000860319 7001_ $$0P:(DE-HGF)0$$aHoeber, H.$$b1 000860319 7001_ $$0P:(DE-Juel1)132090$$aEicker, N.$$b2$$ufzj 000860319 7001_ $$0P:(DE-HGF)0$$aGüsken, S.$$b3 000860319 7001_ $$0P:(DE-Juel1)132179$$aLippert, Th.$$b4$$ufzj 000860319 7001_ $$0P:(DE-HGF)0$$aSchilling, K.$$b5 000860319 7001_ $$0P:(DE-HGF)0$$aStruckmann, T.$$b6 000860319 7001_ $$0P:(DE-HGF)0$$aUeberholz, P.$$b7 000860319 7001_ $$0P:(DE-HGF)0$$aViehoff, J.$$b8 000860319 77318 $$2Crossref$$3journal-article$$a10.1103/physrevd.60.074502$$b : American Physical Society (APS), 1999-09-03$$n7$$p074502$$tPhysical Review D$$v60$$x0556-2821$$y1999 000860319 773__ $$0PERI:(DE-600)2844732-3$$a10.1103/PhysRevD.60.074502$$gVol. 60, no. 7, p. 074502$$n7$$p074502$$tPhysical review / D$$v60$$x0556-2821$$y1999 000860319 909CO $$ooai:juser.fz-juelich.de:860319$$pextern4vita 000860319 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)132090$$aForschungszentrum Jülich$$b2$$kFZJ 000860319 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)132179$$aForschungszentrum Jülich$$b4$$kFZJ 000860319 9101_ $$0I:(DE-HGF)0$$6P:(DE-HGF)0$$aExternal Institute$$b5$$kExtern 000860319 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000860319 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bPHYS REV D : 2016 000860319 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000860319 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search 000860319 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC 000860319 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List 000860319 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000860319 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000860319 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000860319 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences 000860319 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5 000860319 980__ $$ajournal 000860319 980__ $$aEDITORS 000860319 980__ $$aI:(DE-Juel1)JSC-20090406 000860319 980__ $$aI:(DE-Juel1)NIC-20090406 000860319 9801_ $$aEXTERN4VITA
