Abstract :Using the most general model-independent effective Hamiltonian comprising local four-Fermi operators insert ignore into journalissuearticles values(scalar, vector, and tensor operators);, we study the sensitivity of the zero position of the lepton asymmetry to the new operators beyond the Standard Model insert ignore into journalissuearticles values(SM); in the B \rightarrow K\ell+\ell- decay. It is found that among all operators, only the scalar and tensor operators contribute to the forward-backward asymmetry, in which case the forward-backward asymmetry has a non-vanishing value.
