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.
