J. Shigemitsu et Cj. Morningstar, PERTURBATIVE MATCHING OF THE NRQCD HEAVY-LIGHT AXIAL CURRENT, Nuclear physics. B, Proceedings supplement, 63, 1998, pp. 341-343
A one-loop matching calculation between Lattice NRQCD aad full QCD for
the heavy-light axial current is described and the effects of renorma
lization on f(B) are discussed.
