| - | * **Where is quark/gluon discrimination actually useful?** Examples: | + | * **Where is quark/gluon discrimination actually useful?** One complication is that many other analysis selections are already purifying the selection (e.g. requiring two forward jets with large mjj already suppresses gluon jets for VBF/VBS). Examples: |

| - | * **Extraction of the strong coupling constant** This was a main focus of the last Les Houches and we plan on at least having a discussion about this one of the days. As part of this, we may want to do a short study of the difference between inclusive jets (F. Ringer et al.) and dijets. | + | * **Extraction of the strong coupling constant** This was a main focus of the last Les Houches and we plan on at least having a discussion about this one of the days.

| - | * **Tuning with jet substructure** One motivation for performing measurements of jet structure is to improve MC tunes. It would be good to understand which observables are actually sensitive to which parameters, taking note of what has already been measured. IRC safe observables may not be so useful for tuning. Another sub-topic: can we understand the ATLAS jet pull angle measurement from the point of view of parameter variations? (quite significant tension between Pythia and data). | + | * **Tuning with jet substructure** One motivation for performing measurements of jet structure is to improve MC tunes.

We could revisit this topic for Higgs and/or BSM (top is already quite well-covered with 1902.09914). | + | * **Tagging** There was a big effort to understand light 2-prong tagging last Les Houches.
