The predicted new quark flavour, c = charm [3] could be added to the hadron spectroscopy by the interpretation of the new particles as c c¯ bound states. It was argued that the new system is nonrelativistic: Charmonium [4]. Whereas the old mesons suffered from the fact that the quarks are extremely relativistic (mass differences are of the order of the masses themselves), in Charmonium the heavy (≈ 1.5 GeV) c-quarks should move relatively slowly, β2 = (v/c)2 ≈ 0.2. The well known powerful methods of exploring a nonrelativistic system could be used. This was the source of real excitement about the new particles. 000396404 536__ $$0G:(DE-HGF)POF3-899$$a899 - ohne Topic (POF3-899)$$cPOF3-899$$fPOF III$$x0 000396404 588__ $$aDataset connected to CrossRef Book, INSPIRE 000396404 650_7 $$2INSPIRE$$aLECTURES 000396404 650_7 $$2INSPIRE$$aQUARK: QUARKONIUM 000396404 650_7 $$2INSPIRE$$aQUARK: CHARMONIUM 000396404 650_7 $$2INSPIRE$$aQUANTUM MECHANICS: SCHROEDINGER EQUATION 000396404 650_7 $$2INSPIRE$$aSCALING: SCHROEDINGER EQUATION 000396404 650_7 $$2INSPIRE$$abottom 000396404 650_7 $$2INSPIRE$$aQUARK ANTIQUARK: BOUND STATE 000396404 650_7 $$2INSPIRE$$aQUARK: CHARGE 000396404 650_7 $$2INSPIRE$$aDUALITY 000396404 650_7 $$2INSPIRE$$aFINE STRUCTURE: CHARMONIUM 000396404 650_7 $$2INSPIRE$$aHYPERFINE STRUCTURE: CHARMONIUM 000396404 650_7 $$2INSPIRE$$aPSI MESONS: ENERGY LEVELS 000396404 650_7 $$2INSPIRE$$aPSI MESONS: RADIATIVE DECAY 000396404 650_7 $$2INSPIRE$$aRADIATIVE DECAY: PSI MESONS 000396404 650_7 $$2INSPIRE$$aTRANSITION: ELECTRIC 000396404 650_7 $$2INSPIRE$$aTRANSITION: MAGNETIC 000396404 650_7 $$2INSPIRE$$aSCALING: RADIATIVE DECAY 000396404 650_7 $$2INSPIRE$$aRADIATIVE DECAY: SCALING 000396404 650_7 $$2INSPIRE$$aX(2830) 000396404 650_7 $$2INSPIRE$$aNEW PARTICLE: CHI(3450) 000396404 650_7 $$2INSPIRE$$aNEW PARTICLE: CHI(3590) 000396404 650_7 $$2INSPIRE$$aELECTRON POSITRON: ANNIHILATION 000396404 650_7 $$2INSPIRE$$aANNIHILATION: ELECTRON POSITRON 000396404 650_7 $$2INSPIRE$$aQUANTUM CHROMODYNAMICS 000396404 650_7 $$2INSPIRE$$aJET 000396404 650_7 $$2INSPIRE$$aBIBLIOGRAPHY 000396404 693__ $$0EXP:(DE-MLZ)NOSPEC-20140101$$5EXP:(DE-MLZ)NOSPEC-20140101$$eNo specific instrument$$x0 000396404 7001_ $$0P:(DE-HGF)0$$aKrasemann, H.$$b1 000396404 773__ $$a10.1007/978-3-7091-8574-2_4 000396404 8564_ $$uhttps://bib-pubdb1.desy.de/record/396404/files/7905292.pdf$$yOpenAccess 000396404 8564_ $$uhttps://bib-pubdb1.desy.de/record/396404/files/7905292.gif?subformat=icon$$xicon$$yOpenAccess 000396404 8564_ $$uhttps://bib-pubdb1.desy.de/record/396404/files/7905292.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 000396404 8564_ $$uhttps://bib-pubdb1.desy.de/record/396404/files/7905292.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000396404 8564_ $$uhttps://bib-pubdb1.desy.de/record/396404/files/7905292.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000396404 8564_ $$uhttps://bib-pubdb1.desy.de/record/396404/files/7905292.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000396404 909CO $$ooai:bib-pubdb1.desy.de:396404$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000396404 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-HGF)0$$aDeutsches Elektronen-Synchrotron$$b0$$kDESY 000396404 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-HGF)0$$aDeutsches Elektronen-Synchrotron$$b1$$kDESY 000396404 9131_ $$0G:(DE-HGF)POF3-899$$1G:(DE-HGF)POF3-890$$2G:(DE-HGF)POF3-800$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bProgrammungebundene Forschung$$lohne Programm$$vohne Topic$$x0 000396404 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000396404 9201_ $$0I:(DE-H253)DESY_-2012_-20170516$$kDESY(-2012)$$lDESY Retrocat$$x0 000396404 980__ $$aintrep 000396404 980__ $$aVDB 000396404 980__ $$aUNRESTRICTED 000396404 980__ $$areport 000396404 980__ $$aI:(DE-H253)DESY_-2012_-20170516 000396404 9801_ $$aFullTexts
