Description

We report on a calculation of the charmonium contribution to the decay $B \rightarrow Kll$ 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.
