First results of the measurement of the interaction cross section between primary protons and air nuclei with the ARGO-YBJ experiment are reported. The analysis is based on the flux attenuation for different atmospheric depths (i.e. zenith angles) and can exploit the detector capabilities of selecting the shower development stage by means of the size, hit density and both time and lateral profile measurements. The effects of shower fluctuations and the contribution of heavier primaries have been also considered.

Abstract
First results of the measurement of the interaction cross section between primary protons and air nuclei with the ARGO-YBJ experiment are reported. The analysis is based on the flux attenuation for different atmospheric depths (i.e. zenith angles) and can exploit the detector capabilities of selecting the shower development stage by means of the size, hit density and both time and lateral profile measurements. The effects of shower fluctuations and the contribution of heavier primaries have been also considered.File in questo prodotto:
