We compute the normalization of the form factor entering the ...... decay amplitude by using numerical simulations of QCD on the lattice. From our study with ...... dynamical light quarks, and by employing the maximally twisted Wilson quark action, we obtain in the continuum limit ....... We also compute the scalar and tensor form factors in the region near zero recoil and find ......, ......, for ....... The latter results are useful for searching the effects of physics beyond the Standard Model in ...... decays. Our results for the similar form factors relevant to the non-strange case indicate that the method employed here can be used to achieve the precision determination of the ...... decay amplitude as well.
