摘要：

The B meson decay constant can be measured on the lattice using the static effective field theory. We present the order αs comparison of the matrix elements of heavy-light bilinears measured on the lattice using Wilson fermions to their counterparts in the continuum. The time component of the axial current determines fB. A subtlety associated with a linear divergence in the heavy quark self-energy is discussed. © 1990.
