overlap with other systems. It could be argued that one should classify 
individual initial-state partons by <i>pT</i> rather than the system 
as a whole. However, for final-state radiation, a soft gluon radiated off 
a hard parton is actually produced at late times and therefore probably 
less likely to reconnect. In the balance, a classification by system 
<i>pT</i> scale appears sensible as a first try.
