The average number of "toward" charged particles
(PT > 0.5 GeV/c, |eta| < 1, including chgjet1)
as a function of the transverse momentum of the leading charged jet. Each point
corresponds to the <Nchg> in a 1 GeV/c bin. The data are compared with the QCD
Monte-Carlo model predictions of ISAJET 7.32, with its default parameters and
PT(hard) > 3 GeV/c. The predictions of ISAJET are
divided into three categories: charged particles that arise from the break-up of the beam particles
("beam-beam remnants"), charged particles that arise from
initial-state radiation, and charged
particles that result from the outgoing jets plus final-state radiation.
The Monte-Carlo model predictions have been corrected for the CTC track finding efficiency
(8% of the charged tracks are, on the average, removed) and have an uncertainty
(statistical plus systematic) of about 5%.
