1 Oct 2001 | | Journal: | Nucl.Phys.Proc.Suppl. 106 (2002) 406-408 | | Subject: | hep-lat | | Abstract: | We show results for the B meson decay constant calculated both for B mesons at rest and those with non-zero momentum and using both the temporal and spatial components of the axial vector current. It is an important check of lattice systematic errors that all these determinations of f_B should agree. We also describe how well different smearings for the B meson work at non-zero momentum - the optimal smearing has a narrow smearing for the b quark. | | Source: | arXiv, hep-lat/0110003 | | Services: | Forum | Review | PDF | Favorites | |
