The average number of "transverse" charged particles
(PT > 0.5 GeV/c, |eta| < 1)
as a function of the transverse momentum of the leading charged jet compared with the QCD
Monte-Carlo model predictions PYTHIA 6.115 with different structure functions and different
multiple parton interaction
parameters and with PT(hard) > 0 GeV/c. 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%.
