We present experimental details from a study of hadron jet production at high transverse
momentum (p⊥) in 130 and 200 GeV hadron-proton collisions. Jet definition and
acceptance of the apparatus are discussed thoroughly. Jet cross sections are measured for
p, π−, π+, K−, K+, and p incident on a liquid hydrogen target. These cross sections depend
strongly on the number of valence quarks in the beam. The p⊥ dependence of the jet cross
section is measured to be significantly flatter than that for single particles. We show that a …

Jet-like structure in hadronic interactions was first observed at the CERN intersecting
storage rings in events triggered by single high-p j_ neutral pions [1]. Since then, we have
triggered directly on jets of particles of high collective transverse momentum [2]. Jets are of
substantial current interest because the possibility exists that they arise in hadron-hadron
collisions from the hard scattering and subsequent fragmentation of constituent partons. We
present experimental details of jet studies from the main run of E260 at the Fermilab multi …
