Contributions to B\to \pi l \nu decay from 1/m_Q order corrections are
analyzed in the heavy quark effective field theory (HQEFT) of QCD. Transition
wave functions of 1/m_Q order are calculated through light cone sum rule (LCSR)
within the HQEFT framework. The results are compared with those from other
approaches.
