  • Update on the Combined Analysis of Muon Measurements from Nine Air Shower Experiments
    ICRC 2021 THE ASTROPARTICLE PHYSICS CONFERENCE ONLINE ICRC 2021Berlin | Germany THE ASTROPARTICLE PHYSICS CONFERENCE th Berlin37 International| Germany Cosmic Ray Conference 12–23 July 2021 Update on the Combined Analysis of Muon Measurements from Nine Air Shower Experiments Dennis Soldin0,∗ for the EAS-MSU, IceCube, KASCADE-Grande, NEVOD-DECOR, Pierre Auger, SUGAR, Telescope Array, and Yakutsk EAS Array Collaborations (a complete list of authors can be found at the end of the proceedings) 0Bartol Research Institute, Dept. of Physics and Astronomy University of Delaware, Newark, DE 19716, USA E-mail: [email protected] Over the last two decades, various experiments have measured muon densities in extensive air showers over several orders of magnitude in primary energy. While some experiments observed differences in the muon densities between simulated and experimentally measured air showers, others reported no discrepancies. We will present an update of the meta-analysis of muon measurements from nine air shower experiments, covering shower energies between a few PeV and tens of EeV and muon threshold energies from a few 100 MeV to about 10 GeV. In order to compare measurements from different experiments, their energy scale was cross-calibrated and the experimental data has been compared using a universal reference scale based on air shower simulations. Above 10 PeV, we find a muon excess with respect to simulations for all hadronic interaction models, which is increasing with shower energy. For EPOS-LHC and QGSJet-II.04 the significance of the slope of the increase is analyzed in detail under different assumptions of the individual experimental uncertainties. arXiv:2108.08341v2 [astro-ph.HE] 20 Aug 2021 37th International Cosmic Ray Conference (ICRC 2021) July 12th – 23rd, 2021 Online – Berlin, Germany ∗Presenter © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND 4.0).

  • Cherenkov Light Imaging in Astroparticle Physics
    Cherenkov light imaging in astroparticle physics U. F. Katz Erlangen Centre for Astroparticle Physics, Friedrich-Alexander University Erlangen-N¨urnberg, Erwin-Rommel-Str. 1, 91058 Erlangen, Germany Abstract Cherenkov light induced by fast charged particles in transparent dielectric media such as air or water is exploited by a variety of experimental techniques to detect and measure extraterrestrial particles impinging on Earth. A selection of detection principles is discussed and corresponding experiments are presented together with breakthrough-results they achieved. Some future develop- ments are highlighted. Keywords: Astroparticle physics, Cherenkov detectors, neutrino telescopes, gamma-ray telescopes, cosmic-ray detectors 1.

  • History of High-Energy Neutrino Astronomy
    History of high-energy neutrino astronomy C. Spiering DESY, Platanenallee 6, D-15738 Zeuthen, Germany This talk sketches the main milestones of the path towards cubic kilometer neutrino telescopes. It starts with the first conceptual ideas in the late 1950s and describes the emergence of concepts for detectors with a realistic discovery potential in the 1970s and 1980s. After the pioneering project DUMAND close to Hawaii was terminated in 1995, the further development was carried by NT200 in Lake Baikal, AMANDA at the South Pole and ANTARES in the Mediterranean Sea. In 2013, more than half a century after the first concepts, IceCube has discovered extraterrestrial high-energy neutrinos and opened a new observational window to the cosmos { marking a milestone along a journey which is far from being finished. 1 From first concepts to the detection of atmospheric neutrinos The initial idea of neutrino astronomy beyond the solar system rested on two arguments: The first was the expectation that a supernova stellar collapse in our galaxy would be accompanied by an enormous burst of neutrinos in the 5-10 MeV range. The second was the expectation that fast rotating pulsars must accelerate charged particles in their Tera-Gauss magnetic fields. Either in the source or on their way to Earth they must hit matter, generate pions and neutrinos as decay products of the pions. The first ideas to detect cosmic high energy neutrinos underground or underwater date back to the late fifties (see 1 for a detailed history of cosmic neutrino detectors). In the 1960 Annual Review of Nuclear Science, K.

IceCube was designed to detect high energy neutrinos from extreme as- trophysical environments which are potential cosmic ray acceleration sites, such as active galac- tic nuclei, gamma ray bursts and supernova remnants. e discovery of astrophysical neutrinos by IceCube in 2013 heralded the beginning of neutrino astronomy, and we continue to collect data and explore the properties and potential sources of these neutrinos. An expanded succes- sor called IceCube-Gen2 is in development, with updated optical sensors and calibration devices, and an expanded surface veto. e IceCube-Gen2 detector will search for the sources of cosmic neutrinos and will also include an infill component which will investigate fundamental neutrino physics using atmospheric neutrinos. I will discuss the latest results from IceCube, and the status of IceCube-Gen2.

How are UHECRs accelerated to such extreme energies? Are there multiple types of sources and acceleration mechanisms? Do UHECRs consist of both protons and heavier nuclei, and how does the composition evolve as a function of energy? In order to address these questions, the goals for the next decade will be to: identify one or more nearby UHECR sources, refine the spectrum and composition of the highest-energy Galactic and extragalactic cosmic-rays, exploit extensive air showers (EAS) to probe particle physics inac- cessible at accelerators, and develop the techniques to make charged-particle astronomy a reality. This agenda is largely achievable in the next decade, thanks to major experimental upgrades underway and new ground observatories and space missions in development.
