摘要：
We explore the splitting between flavor singlet and non-singlet mesons in charmonium using unquenched lattice QCD. The non-perturbatively improved clover formalism is used for both the sea and valence quarks. This has implications for lattice calculations of the hyperfine splitting in charmonium.
