Research Abstract

In order to clarify various properties of heavy quarkonia, we compute the inter-quark potential by using lattice QCD simulations within the quenched approximation, which contains relativistic corrections up to the second order of 1/m expansion in the effective field theory for heavy quarkonium called potential nonrelativistic QCD.
