Abstract

The production of large-q_t gluon jets in very-high-energy hadron collisions near the center of the rapidity plateau is studied in perturbative QCD. It is shown that at s → ∞ the processes with q_t ∼ Λ exp[1.26(ln s)^{1 2}] become the main source of secondary hadrons. The inclusive cross sections dσ^jet dy dq_t², the multiplicity distribution dn^jet dy and the transverse energy distribution dE_t dy are calculated at SPS collider energy. The hadron spectrum dσ^h dp_t² is obtained using a reasonable gluon fragmentation function. It appears to be in good agreement with the recent collider data.
