摘要：

We review various B meson decays that require knowledge of the transverse decay constant of the b(1)(1235) meson. We report on an exploratory lattice QCD calculation of the transverse decay constant of the b(1) meson. The lattice QCD calculations used unquenched gauge configurations, at two lattice spacings, generated with two flavours of sea quarks. The twisted mass formalism is used. (C) 2010 Elsevier B.V.
