Abstract
We investigate the ground-state heavy quarkonium and its first excited state with quantum numbers . The masses and decay constants of these charmonium states are computed using two-point QCD sum rule method by including quark, gluon and mixed condensates up to dimension-8. We compare our numerical results with the available experimental data as well as existing theoretical predictions in the literature.
