Description

Using analytic results obtained in a meson effective theory which includes all infrared sensitive logs, we build a dedicated Monte Carlo to describe QED corrections in $\bar{B}^{0} \rightarrow \bar{K}^{0} \ell \ell$ processes.
We present a detailed numerical comparison of the impact of QED corrections in our framework with respect to the ones obtained when simulated using the general-purpose photon-shower tool PHOTOS. In addition, our framework allows us to study the impact QED corrections in interference effects between the rare mode and the charmonium resonances.
