“…with the mean target mass of air being m air ≈ 14.45 m p = 24160 mb g/cm 2 [1]. It is, therefore, not surprising that there is a long history of attempts to infer this cross section from high-energy cosmic ray data [2][3][4][5][6][7][8][9][10][11][12][13][14][15]. A compilation of published proton-air cross section measurements and predictions of ultra-high energy hadronic interaction models is shown in Fig.…”

The analysis of high-energy air shower data allows one to study the proton-air cross section at energies beyond the reach of fixed target and collider experiments. The mean depth of the first interaction point and its fluctuations are a measure of the proton-air particle production cross section. Since the first interaction point in air cannot be measured directly, various methods have been developed in the past to estimate the depth of the first interaction from air shower observables in combination with simulations. As the simulations depend on assumptions made for hadronic particle production at energies and phase space regions not accessible in accelerator experiments, the derived cross sections are subject to significant systematic uncertainties. The focus of this work is the development of an improved analysis technique that allows a significant reduction of the model dependence of the derived cross section at very high energy. Performing a detailed Monte Carlo study of the potential and the limitations of different measurement methods, we quantify the dependence of the measured cross section on the used hadronic interaction model. Based on these results, a general improvement to the analysis methods is proposed by introducing the actually derived cross section already in the simulation of reference showers. The reduction of the model dependence is demonstrated for one of the measurement methods. ‡ Corresponding author, ralf.ulrich@kit.edu § KIT is the cooperation of University Karlsruhe and Forschungszentrum Karlsruhe On the measurement of the proton-air cross section using air shower data

“…All data above 100 TeV are based on the analysis of EAS data [7][8][9][10][11][12][13]. Also the ARGO-YBJ measurements around 10 TeV are originating from a high altitude EAS array [14]. The data at lower energies stem from unaccompanied hadron analyses [2][3][4][5][6].…”

In the framework of eikonalized mini-jet model, contributions from gluon recombination effects are studied for the free proton in pp and pp reactions. The nuclear configurational entropy is then used to calculate the main parameters to estimate the total proton cross sections for the recent data LHC, also corroborating to previous developments. Photoproduction cross sections with vector meson dominance and saturation effects for both total hadronic and photonic cross sections at a high energy regime are investigated. Extreme points of the configurational entropy provide the experimentally obtained cross sections within an optimal root-mean-square deviation.

In this report we review the important progress made in recent years towards understanding the experimental data on ultra-high-energy (E 10 9 GeV) cosmic rays. We begin with a general survey of the available data, including a description of the energy spectrum, the nuclear composition, and the distribution of arrival directions. At this point we also give a synopsis of experimental techniques. After that, we introduce the fundamentals of cosmic ray acceleration and energy loss during propagation, with a view of discussing the conjectured nearby sources. Next, we survey the state of the art regarding the high-and ultra-high-energy cosmic neutrinos which may be produced in association with the observed cosmic rays. These neutrinos could constitute key messengers identifying currently unknown cosmic accelerators, possibly in the distant universe, because their propagation is not influenced by background photon or magnetic fields. Subsequently, we summarize the phenomenology of cosmic ray air showers. We describe the hadronic interaction models used to extrapolate results from collider data to ultra-high energies and the main electromagnetic processes that govern the longitudinal shower evolution. Armed with these two principal shower ingredients and motivation from the underlying physics, we describe the different methods proposed to distinguish the primary particle species. In the end, we explore how ultra-high-energy cosmic rays can be used as probes of beyond standard model physics models.
