Direct evidence for the emergence of jets in events triggered on large transverse energy in pp collisions at $\sqrt{s}$ = 63 GeV
The authors present data obtained from a 1.7 sr hadron calorimeter, triggered on transverse energy, in pp collisions at \sqrt{s}=63 GeV at the CERN-ISR. From the change in the distribution of energy in the calorimeter, they extract the cross section for two-constituent hard scattering for p/sub T/ b...

| description | The authors present data obtained from a 1.7 sr hadron calorimeter, triggered on transverse energy, in pp collisions at \sqrt{s}=63 GeV at the CERN-ISR. From the change in the distribution of energy in the calorimeter, they extract the cross section for two-constituent hard scattering for p/sub T/ between 6 and 14 GeV at y=0. The decrease of this jet cross section over this p/sub T/ range is consistent with exp (-bp/sub T/), with b=(1.02+or-0.09) GeV/sup -1/. The slope and normalization of the cross section agree well with a QCD motivated Monte Carlo model. The ratio between jet and single particle cross sections ((d sigma /sub JET//dp/sub T/)/(d sigma (\pi^{0})/dp/sub T/)) mod /sub y=0/ changes from about 200 at 6 GeV to about 1500 at 14 GeV. |
