Search of the tensor glueball: The identification of resonances in the mass region 1.9–2.4 GeV Original Research Article

The result of the partial wave analysis of Crystal Barrel data on View the MathML source and ηη′ combined with earlier data on View the MathML source and polarization for View the MathML source is presented. The polarization data separate cleanly states with L = J ± 1, while Crystal Barrel data provide possibility to define quark content of the observed resonances. Along with other states, four I = 0, JPC = 2++ resonances are identified. All 2+ resonances have flavour composition close to View the MathML source, with rather little View the MathML source component. The possible nonet classification of the found states is discussed.
