Results from a Hadron Jet Experiment at Sqrt S = 19.4 and 27.4 GeV

摘要

In Fermilab experiment E609 we have studied the production of high p/sub t/ hadron jets by beams of protons at 200 and 400 GeV/c and pions at 200 GeV/c. Results for the single-jet and di-jet cross sections are given and are compared to QCD predictions. Leading-particle charge ratios from di-jet events are given and compared to QCD-motivated predictions. Evidence is presented concerning a higher twist effect in pi p interactions as predicted by Berger and Brodsky. Preliminary results on high transverse energy events from nuclear targets are given. Finally, we present comparisons of our pp high E/sub t/ data with predictions from two Monte Carlo models. 12 references. (ERA citation 10:017400)
