Abstract
We present the results of quenched charmonium spectrum for S- and P-states, obtained by a relativistic heavy quark method on anisotropic lattices. Simulations are carried out using the standard plaquette gauge action and a meanfield-improved clover quark action at a −1 t = 3–6 GeV with the renormalized anisotropy fixed to ξ ≡ a s / a t = 3. We study the scaling of our fine and hyperfine mass splittings, and compare with previous results.
