摘要：

Matrix elements of heavy-light bilinears measured on the lattice are compared to their continuum counterparts. The heavy quark is treated using the static effective field theory, and the light quark is treated as a staggered fermion. The time component of the axial current is the bilinear used to determine fB. We derive identities which simplify the calculations involving staggered fermions by reducing them to calculations involving naive fermions. © 1990.
