Abstract:
Ultrahigh energy cosmic ray air showers probe particle physics at energies beyond the reach of accelerators. Here we introduce a new method to test hadronic interaction models without relying on the absolute energy calibration, and apply it to events with primary energy 6-16 EeV (ECM=110-170 TeV), whose longitudinal development and lateral distribution were simultaneously measured by the Pierre Auger Observatory. The average hadronic shower is 1.33±0.16 (1.61±0.21) times larger than predicted using the leading LHC-tuned models EPOS-LHC (QGSJetII-04), with a corresponding excess of muons. © 2016 American Physical Society.

- 261 of the 411 events have an (Equation presented) value so deep or shallow that the LP cannot be reproduced with all primaries for both HEGs, e.g., 209 (230) events cannot be described as Fe, and 32 (10) cannot be described as a proton, in EPOS-LHC (QGSJetII-04), respectively; Ave, M., (2011) Proceedings of the 32nd International Cosmic Ray Conference (ICRC), Beijing, China, p. 178

- The potential sensitivity to (Equation presented) arises in spite of the narrow primary energy range, because individual nucleons in a primary of mass (Equation presented) carry energy (Equation presented). To investigate this we let (Equation presented), where (Equation presented) is the rescaling factor for proton primaries at (Equation presented). We take (Equation presented) as the fiducial value, motivated by Ref. [31], which achieves (Equation presented) by converting (Equation presented)'s and (Equation presented)'s to other mesons, resulting in (Equation presented) for EPOS and 0.01-0.02 for QGSJet. Reanalyzing with (Equation presented), (Equation presented) changes negligibly, and (Equation presented) for EPOS; Pierog, T., (2013) Eur. Phys. J. Web Conf., 52, p. 03001
