Description
We investigate qualitatively the relative performance of various Monte Carlo event generators (including Pythia8, and Whizard3) for generating the two-photon back ground in the leptonic and hadronic final states at the FCC-ee. We consider e+e− interactions at the Z pole, where the two-photon background is a non-negligible background for various electroweak precision analyses such as the muon and hadronic cross-sections. The two-photon background is of particular interest due to simulation difficulties of the γγ → hadron-hadron processes. We primarily study various kinematic variables for simulations of e+e− → γγ → e+e− + µµ interactions. We extend this analysis to e+e− → e+e− + hadrons interactions.
