  • 摘要:We report our exploratory study on the matching condition of HQET with QCD including 1=m corrections. We introduce a new observable from the dependence of the heavy-light effective energy on the twisted boundary condition parameter q , which could be used to match the kinetic term ~D2=2m. Carrying out quenched QCD simulations for fixed lattice spacing in small volumes with O(a)-improved Wilson fermions, we study the 1=m dependence of this observable, from which the static limit and 1=m coefficient can be extracted. We also compare our preliminary result with HQET.
