+ | Find and visualize overlaps in a model-independent way, without generating events. Directly sample the event selection. Targeted for analysis design phase. | ||
+ | |||
+ | * Start from the analysis description, which lists objects and event selections. | ||
+ | * Construct a feature space from all mathematically orthogonal variables (e.g. MET, jet1.pt, jet2.pt, electron1.eta, ...). | ||
+ | * Randomly sample the feature space for each analysis. | ||
+ | * Use the sampled points to compute values for variables such as HT(jets), dphi(jets), MT(lepton, MET), etc. | ||
+ | * Compare feature spaces between analyses, find and visualize overlaps and exclusions. | ||
