Illustration of the average "shape" of a proton-antiproton collision at 1.8 TeV in which there was a leading 20 GeV/c charge particle jet. There are, on the average, 8.7 charged particles in the "toward" region (including the particles in chgjet1), 2.5 in the "transverse" region, and 4.9 in the "away" region. The charged particles have PT > 0.5 GeV/c and |eta| < 1 and the data has been multiplied by 1.09 to correct for the track finding efficiency. (Return)
