Quenched charmonium spectrum on anisotropic lattices

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 $a_t^{-1}=3$--6 GeV with the renormalized anisotropy fixed to $\xi \equiv a_s/a_t=3$. We study the scaling of our fine and hyperfine mass splittings, and compare with previous results.
