The dataset consists of simulated events of electron-positron pairs (e+e−) with flat transverse momentum pT distribution pT ∈ [1,200] GeV, with Phase 2 conditions, 200 pileup, V11 geometry, HLT TDR Summer20 campaign The original dataset (CMS-internal). This derived dataset in ROOT format contains generator-level particle and simulated detector information. More information about how the dataset is derived is available at this TWiki (CMS-internal). A description of each variable is below.
