Abstract
We report on a calculation of the charmonium contribution to the decay $B \rightarrow K\ell^+\ell^-$ using lattice simulations with 2+1 flavors of Mobius domain wall fermions.
We focus on the region of $q^2$ below the $J/\psi$ resonance and test the factorization approximation to estimate the amplitude.
We show a possible discrepancy between lattice calculation and factorization method for the non-factorizable contribution.
