We propose a new search for a diphoton resonance in the $e^+e^-+\gamma\gamma$ final state at Belle II that improves the expected reach compared to the $\gamma+\gamma\gamma$ channel in most of the available mass range. For simplicity we show our results in the simple parameter space of an ALP coupled solely to Standard Model photons. In addition, we show how an extension of the forward coverage of Belle II, or another similar experiment at the high intensity frontier, could improve the reach in our channel. We show that such a forward extension can be advantageous even with a loss of a factor 100 in luminosity compared to Belle II.

Original abstract
We propose a new search for a diphoton resonance in the $e^+e^-+\gamma\gamma$ final state at Belle II that improves the expected reach compared to the $\gamma+\gamma\gamma$ channel in most of the available mass range. For simplicity we show our results in the simple parameter space of an ALP coupled solely to Standard Model photons. In addition, we show how an extension of the forward coverage of Belle II, or another similar experiment at the high intensity frontier, could improve the reach in our channel. We show that such a forward extension can be advantageous even with a loss of a factor 100 in luminosity compared to Belle II.

The photons need also to be separated from the electron to give rise to a clean final state, thus we require for all $e^±$-photon pairs [equation] The angular separation and energy requirements of <ref> guarantee the convergence of the perturbative expansion so that both our signal and background samples are generated with v2.7.3 [ref] at leading order in perturbation theory.
