 +===== Notes for Jesse for Preparing Summary Talk =====

 +  * Quark is more of an adjective than a noun.
 +  * Pseudo-quark? ​ (That language doesn'​t go over very well.)

 +==== What is a Quark Jet? ====

 +(From ill-defined to well-defined)
 +
 +  * A quark parton
 +  * A Born-level quark parton
 +  * The initiating quark parton in a final state shower
 +  * An eikonal line with baryon number 1/3 and carrying triplet color charge
 +  * A quark operator that appears in a hard matrix element in the context of a factorization theorem.
 +  * A parton-level jet object that has been tagged as a quark using a soft-safe flavored jet algorithm (automatically collinear safe if you sum constituent flavors).
 +  * A phase space region (as defined by an unambiguous hadronic fiducial cross section measurement) that yields an enriched sample of quarks (as interpreted by some suitable, though fundamentally ambiguous, criterion).  ​

 +(Sometimes people think we care about the top of the list while we are really focused entirely on the bottom.)
