Özet

Using the most general effective Hamiltonian comprising scalar, vector and tensor type interactions, we have computed the branching ratio, the forward-backward (FB) asymmetry and the normalized FB asymmetry as functions of the new Wilson coefficients. It is found that the branching ratio depends on all new coefficients, but the asymmetries can be analyzed in terms of only one Wilson coefficient.
