  "abstract": "The dressed heavy quark mass \\hat{m}_Q=m_Q+\\bar{{\\Lambda}} with \\bar{{\\Lambda}} 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/\\hat{m}_Q 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/\\hat{m}_Q expansion is more favorable in application. The extraction of |V_{cb}| from exclusive B decays is studied by using such a new expansion approach.",
