33. Xmax Uncertainty from Extrapolation of Cosmic Ray Air Shower Parameters.

Recent measurements at the LHC of the p-p total cross section have reduced the uncertainty in simulations of cosmic ray air showers, in particular of the depth of shower maximum. However, there is a remaining uncertainty due to the total cross section, multiplicity, and elasticity. Uncertainties due to extrapolations from accelerator data in the p-p center of mass, to 250 TeV...

Hadronic cross sections relevant to the air shower development are difficult to calculate from the first principle. Instead, phenomenological models are developed, and they are tested using the accelerator data. Because the Large Hadron Collider provides the highest collision energy, 13TeV in the center-of-momentum system and 10^{17} eV cosmic-ray equivalent energy, it is the best tool to...

24. The resent results from the LHCf experiment

Hiroaki Menjo (Nagoya University (JP))

The LHCf experiment is one of the LHC forward experiment. The LHCf aims to provide critical data for evaluation of hadronic interaction models which are used in MC simulations of air shower developments induced by high energy cosmic-rays. The LHCf detectors measures neutral particles, photons, neutrons and neutral pions, emitted in the very forward region of a LHC interaction point. The...

74. Review of model predictions for extensive air sowers

Tanguy Pierog (KIT)

In detailed air shower simulations, the uncertainty in the prediction of shower observable for different primary particles and energies is currently dominated by differences between hadronic interaction models. With the results of the first run of the LHC, the difference between post-LHC model predictions has been reduced at the same level than experimental uncertainties of cosmic ray...
