Key Points Higgs to Tau Tau analysis The NanoAOD samples required for this analysis include data, simulated signals, and several simulated backgrounds RDataFrame tools are useful for efficiently manipulating data and plotting histograms. Event selection Selection criteria include kinematic limits (momentum and angle), identification, and isolation. Kinematic limits are usually based on detector ranges and the physics process being studied. Identification and isolation criteria depend mostly on your physics analysis goals. Glossary FIXME
