Abstract

Using the lattice NRQCD action for heavy quark, we calculate the heavy quark expansion parameters μ_π² and μ_G² for heavy-light mesons and heavy-light-light baryons. The results are compared with the mass differences among heavy hadrons to test the validity of HQET relations on the lattice.
