A calculation of the tensor form factor ($$f_\mathrm{T}$$fT) 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 $$f_\mathrm{T}$$fT for D-meson decays. For decays of B and D to the K-meson, we calculate the vector form factors ($$f_+$$f+ and $$f_0$$f0). The lattice results are obtained from a quenched $$40^{3}\times 80$$403×80 lattice with an inverse lattice spacing of $$a^{-1}\simeq 4.97$$a-1≃4.97 GeV using the Wilson gauge action and the O(a) improved Wilson action for quarks.
