The Zero Position Of The Forward-Backward Asymmetry In The B \Rightarrow K\Ell^+\Ell^- Decay With New Physics Effects, Altuğ Arda

Turkish Journal of Physics

Using the most general model-independent effective Hamiltonian comprising local four-Fermi operators (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 (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.
