Abstract

The spectrum of charmonium resonances contains a number of unanticipated states along with several conventional quark-model excitations. The hadrons of different quantum numbers J(P) appear in a fairly narrow energy band, where J(P) refers to the spin-parity of a hadron in its rest frame. This poses a challenge for lattice QCD studies of (coupled-channel) meson-meson scattering aimed at the ...
