AbstractAbstract
[en] Using the static approximation for the b-quark, we discuss a lattice calculation of the pseudoscalar B-meson decay constant fB. We test the factorization of the residue of the ground state B-meson pole by considering the matrix of correlators between local and nonlocal Qanti q operators. Calculation of the B-meson wavefunction is discussed. (orig.)
