-As of 7/17/2020, I have updated all files in benchmarks/, adding some clarity, simpler solutions, and NanoEvents support. NanoEvents is what you should be using for most Coffea analyses, especially if they involve NanoAODs, but I have left the old method of constructing JaggedCandidateArrays to access data in the oldbenchmarks/ folder for reference, just in case. The oldbenchmarks/ folder has not been significantly updated; if you are learning Coffea, use benchmarks/!

+As of 1/20/2022, these examples have been contributed by [Nick Smith](https://github.com/nsmith-). They are in the coffea-adl-benchmarks.ipynb notebook and respond to the following queries:
 
 1. Plot the missing ET of all events.
 2. Plot pT of all jets in all events.

 8. For events with at least three leptons and a same-flavor opposite-sign lepton pair, find the same-flavor opposite-sign lepton pair with the mass closest to 91.2 GeV and plot the transverse mass of the missing energy and the leading other lepton.

-1. Plotting the Missing ET (or any event level variable).
-2. Plotting the Jet pT (or any variable that is a per-event array).
-3. Plotting the Jet pT for jets that have an jet pT > 20 GeV and abs(jet eta) < 1.0
-4. Plotting the Missing ET for jets with at least 2 jets with Jet pT > 40 and abs(jet Eta) < 1.0
-5. Plot the opposite-sign muon pair mass for all combinations of muons
-6. Plot the Missing ET for events that have an opposite-sign muon pair mass in the range 60-120 GeV (double loop over single collection, math)
-7. Plot the sum of the pT of jets with pT > 30 GeV that are not within 0.4 from any lepton with pt > 10 GeV (looping over two collections)
-8. For events with at least three leptons and a same-flavor opposite-sign lepton pair, find the same-flavor opposite-sign lepton pair with the mass closest to 91.2 GeV and plot the transverse mass of the missing energy and the leading other lepton.

-Note that for exercise 8, things get a little more complicated as we deal with cross-lepton pairs. A columnar solution to this exists, where we construct a new 'stacked' array of muons and electrons: leptons. This solution is now implemented in benchmarks/. An event loop solution exists and is implemented in the oldbenchmarks/ version, for purposes of comparison. I think you will find the columnar approach to be much nicer!

-I have sought to provide detailed explanations for how each of these things is done in Coffea. Therefore, a lot of the code has verbose comments, which I hope are more helpful than they are distracting!
+A more pedagogical approach to solving these examples is contained within the [coffea-casa-tutorials repository](https://github.com/CoffeaTeam/coffea-casa-tutorials/tree/master/examples), intended to be ran on [coffea-casa](https://github.com/CoffeaTeam/coffea-casa).
