The workshop will start at 9:00 am on January 21 and end at 6:00 pm on January 23.  The Indico page is located here.

Particular topics we hope to address include:

  1. 1.Jets vs. Subjets vs. Particles

Traditionally, a jet was thought of as a proxy for a hard parton. Should we now think of subjets as proxies for particles? What new calibration strategies are need to calibrate events at the subjet level? Can these be reliably validated?

  1. 2.Issues in Soft QCD

Can we characterize what effect pileup mitigation has on the underlying event? What universal statements can be made about hadronization and non-perturbative corrections? How do LHC measurements clarify or bring new perspective to strongly interacting physics?

  1. 3.Hammers & Nails

Are there existing techniques that have not found their best applications? Are there channels or search strategies that are not making full use of measurable jet properties? Are all of our hammers striking the right nails?

  1. 4.Precision Jet Physics

In what measurements is precision understanding of jet/subjet properties most beneficial? Are new precision measurements possible via substructure that would be otherwise inaccessible? What should be the flagship SM measurement for substructure techniques?

  1. 5.The Elegance of Jets

What about jet physics could be thought of as elegant in its own right? What measurements, for example, probe the hadron/parton duality underlying QCD?

  1. 6.Pileup Mitigation and Validation

Several different grooming/subtraction techniques now exist to address pileup mitigation. How should we optimize for universality vs. efficiency in combining them? What effect on calibration & validation schemes does pileup mitigation have?

  1. 7.Jets from Heavy Ions

How do demands on jets in heavy ion application differ from those in collider physics? Can jet substructure techniques be used to answer questions of interest to the heavy ion community? What are the prospects of quark/gluon discrimination in heavy ion events?

  1. 8.Assessing Standard Candles

How robust are our tagging techniques with respect to the topology of the event? E.g.: Are there non-local effects that will make the performance in boosted tops in ttbar production be different from that in Z' -> ttbar? (and similar questions for boson and quark/gluon tagging). How does this impact the calibration and validation of these techniques in data?
