摘要：
Laplace transform QCD sum rules in the infinite mass limit are considered in order to estimate the asymptotic value of the product f(p) square-root M(p). It is shown that (a) mass corrections to the M(Q) --> infinity limit can be calculated; (b) continuum and nonperturbative corrections can be kept well under control; and (c) a quantitative criterion can be formulated to assess when a quark is heavy enough for the scaling law to be valid.
