Description
The important $K_L\rightarrow \mu^+ \mu^-$ decay is complicated by the presence of intermediate states with the same or lower energy than the mass of kaon. To address one of these intermediate states, the two-particle $\gamma\gamma$ state, it is useful to work on a simpler problem which offers the same difficulty --- the $\pi^0 \rightarrow e^+ e^-$ decay. We hope to present preliminary results of a first-principles calculation of the real part of the $\pi^0 \rightarrow e^+ e^-$ decay amplitude to demonstrate the effectiveness of our method.
