Abstract

The cross section for large p_t jet production for transverse momentum 10 ≤ p_t ≤ 20 GeV/c and rapidity 1.6 ≤ η ≤ 2.6 in p-N ( p-'air') interactions is studied from the analysis of multicore Extensive Air Showers recorded in the EAS-TOP calorimeter. The projectiles are the leading particles interacting at atmospheric depths between 250 and 480 cm^-2, the CMS energy of interaction being √s ≈ 500 GeV. The slope of the p_t distribution agrees with the expected one from the p-p̄ collider data at the same CMS energy. The measured jet production cross section in p-N interactions with respect to p-p̄ interactions is (dσ/dp_t)_pN^Jet = (dσ/dp_t)_pp̄^jet. A^α with α = 1.56 ± 0.07 for A= 14.7 (average mass number of 'air' nuclei). Such value is compatible within the experimental uncertainties with the one obtained in p-nucleus accelerator measurements at √s ≃ 30 GeV in the same range of transverse momentum and rapidity. No indication of increase of α with energy, i.e. of the entity of the 'Cronin effect', is found.
