•“Flow vector” 
•Jet is defined by “stable” cone:
•
•Stable cones found by iteration:  start with cone anywhere (and, in principle, everywhere), calculate the centroid of this cone, put new cone at centroid, iterate until cone stops “flowing”, i.e., stable Ž Proto-jets (prior to split/merge)

Ž unique, discrete jets event-by-event (at least in principle)
