To measure matrix elements involving heavy quarks on the lattice, including b and the B meson decay constant, the dependence on the heavy quark mass must &St be extracted analytically. We present the resulting continuum effective field theory action and illustrate its utility by calculating the one-loop renormalization of em arbitrary heavy-light biinear. We also discuss the limits of the approximation.
