Study of Semileptonic and Dileptonic Events in High-Energy Physics Experiments

This study analyzes events with one or two leptons from W boson decays, focusing on generator cuts, offline selection efficiencies, and event characteristics such as jet multiplicity. A comparison between FullSim and FastSim datasets is conducted for a thorough evaluation.

  1. Semileptonic events • 1 lepton from W • pTgen>10 GeV , |h|<2.4 • 1 lepton pT>20 GeV,|h|<2.0 • At least 2 jets (ETRaw>13,|h|<2.4) • Dileptonic events • 2 leptons from W • pT>10 GeV |h|<2.4 • 2 leptons pT>20 GeV, pT>15 GeV |h|<2.0, opposite charge • At least 2 jets (ETRaw>13,|h|<2.4) Generator cuts Off-line selection efficiencies reported etrig based on MC information etrig/off relative to the offline selection
