  • A bstractWe present a spectrum of highly excited charmonium mesons up to around 4.5 GeV calculated using dynamical lattice QCD. Employing novel computational techniques and the variational method with a large basis of carefully constructed operators, we extract and reliably identify the continuum spin of an extensive set of excited states, states with exotic quantum numbers (0+−, 1−+, 2+−) and states with high spin. Calculations are performed on two lattice volumes with pion mass ≈ 400 MeV and… CONTINUE READING
