Charmonium spectrum from quenched anisotropic lattice QCD
Charmonium spectrum from quenched anisotropic lattice QCD
We present a detailed study of the charmonium spectrum using anisotropic lattice QCD. We first derive a tree-level improved clover quark action on the anisotropic lattice for arbitrary quark mass by matching the Hamiltonian on the lattice and in the continuum. The heavy quark mass dependence of the improvement coefficients, …
