摘要：We consider HQET including the first order correction in 1/m. A strategy for the computation of the b-quark mass following the scheme experiment Lattice with amq ¿1 mB = 5.4GeV F1(L1,M),F2(L1,M) ? ? FHQET 1 (L2),FHQET 2 (L2) FHQET 1 (L1),FHQET ¾ 2 (L1) sm(u1) s kin 1 (u1),s kin 2 (u1) L2 = 2L1 is discussed. Only two quantities F1/2 have to be considered in order to match QCD and HQET, since the spin-dependent interaction is easily eliminated due to the spin symmetry of the static theory. Quite simple formulae relate the renormalization group invariant b-quark mass (Mb) to the B-meson mass. All entries in these formulae are non-perturbatively defined and can be computed in the continuum limit of the lattice regularized theory. For the numerically most critical part, we illustrate the cancellation of power divergences by a numerical example. Numerical results for the 1/m correction to Mb, are presented in a companion talk.
