Measurement of the Proton-Air Cross Section at √s=57 TeV with the Pierre Auger Observatory
We report a measurement of the proton-air cross section for particle production at the center-of- mass energy per nucleon of 57 TeV. This is derived from the distribution of the depths of shower maxima observed with the Pierre Auger Observatory: systematic uncertainties are studied in detail. Analyzing the tail of the distribution of the shower maxima, a proton-air cross section of [505±22(stat)-36+28(syst)] mb is found.
