The heavy mass limit in field theory and the heavy quark effective theory
Abstract
We present a derivation of a large mass effective action from the complete theory of elementary interactions, via a sequence of field redefinitions. In this way one derives straightforwardly the ``matching conditions'' of the static effective field theory. Gauge dependent properties of the effective theory are analysed, and relationships between the complete and effective theory are established. We give a general proof that there are no 1/m corrections to the absolute normalization condition of currentinduced flavour changing transitions.
