Abstract

The cross section for large PT jet production for transverse momentum 10 ≤ PT ≤ 30 GeV/c and rapidity interval 1.6 ≤ η ≤ 2.6 in p-N (“Air”) interactions is studied from the analysis of multicore Extensive Air Showers at √s500 GeV, the projectiles being the leading particles interacting at atmospheric depth between 250 and 390 gcm−2. The obtained jet production cross section in p — N interactions with respect to p — p interactions is σp−NJET = σp−pJET. Aα with α = 1.53 ± 0.07 for A ≈ 14. The result agrees with p-nucleus accelerator measurements at √s30 GeV in the same range of transverse momentum and rapidity interval.
