Abstract

In the supersymmetry portal for dark photon productions, each lepton jet is associated with an underlying neutralino. To reconstruct these jets, we first gathered samples of the dilepton decay of dark photons from the Monte Carlo generator PYTHIA 8. For each event, we found leptons with the highest transverse momenta to consider additional leptons within ΔR < 0.5. After the lepton jets were successfully reconstructed, we created an algorithm to match the jets to the generated neutralino pairs. When these matches were found, the difference in ΔR between every neutralino pair and its corresponding lepton jet was calculated. We then used histograms of differences in ΔR, pT, Φ, and η to determine the resolution of the reconstructed lepton jets, which can help us understand the behavior of dark photons.

Lepton Jet Reconstruction, Matching, and Resolution in the SUSY Portal

In the supersymmetry portal for dark photon productions, each lepton jet is associated with an underlying neutralino. To reconstruct these jets, we first gathered samples of the dilepton decay of dark photons from the Monte Carlo generator PYTHIA 8. For each event, we found leptons with the highest transverse momenta to consider additional leptons within ΔR < 0.5. After the lepton jets were successfully reconstructed, we created an algorithm to match the jets to the generated neutralino pairs. When these matches were found, the difference in ΔR between every neutralino pair and its corresponding lepton jet was calculated. We then used histograms of differences in ΔR, pT, Φ, and η to determine the resolution of the reconstructed lepton jets, which can help us understand the behavior of dark photons.
