1/mQ order contributions to B → πlν decay in HQEFT

/ Authors

/ Abstract

Contributions to B → πlν decay from 1/mQ order corrections are analysed in the heavy quark effective field theory (HQEFT) of QCD. Transition wavefunctions of 1/mQ order are calculated through the light cone sum rule within the HQEFT framework. The results are compared with those from other approaches.
