Research Article - Physics


A calculation of the tensor form factor (\(f_\mathrm{T}\)) for rare decays of the B-meson to the K-meson is presented. In order to study the heavy quark mass dependence, we also give \(f_\mathrm{T}\) for D-meson decays. For decays of B and D to the K-meson, we calculate the vector form factors (\(f_+\) and \(f_0\)). The lattice results are obtained from a quenched \(40^{3}\times 80\) lattice with an inverse lattice spacing of \(a^{-1}\simeq 4.97\) GeV using the Wilson gauge action and the O(a) improved Wilson action for quarks.
