摘要The dressed heavy quark mass (m) over capQ = mQ + (Lambda) over bar with (Lambda) over bar being the binding energy is introduced to characterize the heavy hadrons containing a single heavy quark. A heavy quark expansion in terms of the inverse of the dressed heavy quark mass 1/(m) over capQ is presented with a complete decomposition of the full field and integrating out the small components. The heavy quark-antiquark coupling effects are included in the finite mass corrections. It is shown that the 1/(m) over capQ expansion is more favorable in application. The extraction of vertical bar V-cb vertical bar from exclusive B decays is studied by using such a new expansion approach.
