| + | Find and visualize overlaps in a model-independent way, without generating events. Directly sample the event selection. Useful for analysis design phase, or quick comparisons within experiments (e.g. Run2 CMS SUSY pMSSM combination) | ||
| + | |||
| + | * Start from the analysis description, which lists objects and event selections. | ||
| + | * Construct a feature space from all mathematically orthogonal "basic" variables (e.g. MET, jet1.pt, jet2.pt, electron1.eta, ...). | ||
| + | * Randomly sample the feature space for each analysis based on cuts on the feature space components (jet1.pt > 100, MET > 299, etc.). | ||
| + | * Use the sampled points to compute values for "composite" variables such as HT(jets), dphi(jets), MT(lepton, MET), etc. | ||
| + | * Compare feature spaces between analyses, find and visualize overlaps and exclusions. | ||
| + | * As a very simple first step, we simply check if two analyses are disjoint in any of the basic variables. | ||
