Simulation for DarkLight@Ariel

The DarkLight@Ariel experiment will investigate beyond standard model physics at 10s-of-MeV-scale. An anomaly signal at this scale was first observed in 8Be* decay by the ATOMKI group, and last was also observed in other nuclear decay channels. DarkLight will search for evidence of the possible new boson by measuring electron-positron pair production and reconstructing the photon mass using a two-spectrometer setup at the ARIEL electron accelerator at TRIUMF in Canada. In this talk, the simulation process of the experiment will be discussed, and preliminary data of the detector simulation will be shown.
