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). -

SUDBURY in their sights — but will what they see lead physicists to rethink the standard model? Dan Falk investigates. n the subatomic zoo, few particles are as elusive as the neutrino. The Universe is Iawash with them, but they slide through most forms of matter with ease. Billions have passed through your body since you started reading this article. By one estimate, the average neutrino could travel for 1,000 light-years through solid matter before being stopped. This reluctance to interact with matter makes neutrinos difficult to detect. But, almost half a century after they were first spotted, neutrinos have become the focus of intense study. Exciting results from existing detectors, together with plans for new detec- tor projects, promise to make this a busy decade for neutrino hunters. The Sudbury Neutrino Observatory (SNO) in Ontario is poised to illuminate the physics of neutrinos produced by the Sun, and a new detector in Antarctica is making Full house: the detector at Sudbury Neutrino Observatory can detect all three flavours of neutrino. progress towards studying neutrinos from deep space — a first step towards building a particles.

Cavities Radio-frequency cavities drive accelerators across the world, their weird and tune up wonderful metallic structures sustaining strong electromagnetic fields that shunt charged particles to higher energies. Particle physicists have pioneered the development of the most powerful superconducting cavities, and CERN is at the core of this effort. Currently installed in the Super Proton Synchrotron for their first tests in a proton beam are two superconducting “crab” cavities, named for their ability to tilt proton bunches sideways to ensure maximum collision intensity. The technology is at the heart of the high-luminosity LHC upgrade and is based on cavities made entirely from niobium. But CERN is also making huge strides with advanced niobium-coated copper cavities. Once the pinnacle of radio-frequency technology at CERN, driving the upgraded Large Electron Positron collider during the 1990s, niobium– copper cavities are back and even beginning to challenge the performance of their bulk-niobium counterparts. Such developments underpin the recent energy upgrade of the radioactive-beam facility ISOLDE and are key to next-generation accelerators at CERN and elsewhere.

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.

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. -
Major Events and Minor Episodes
IL NUOVO CIMENTO Vol. 37 C, N. 5 Settembre-Ottobre 2014 DOI 10.1393/ncc/i2014-11827-x Colloquia: The Legacy of Bruno Pontecorvo Major events and minor episodes U. Amaldi TERA Foundation and Technische Universit¨at M¨unchen - M¨unchen, Germany Summary. — Bruno Pontecorvo was a freshly graduated twentyone years old physicist when he joined, in the summer of 1934, the research group led by Enrico Fermi. In October the Panisperna boys would make their most important discovery – radioactivity induced by slow neutrons – and shortly thereafter would be parted by personal and historical events. This paper describes some episodes of those early years and of later periods, sketching a portrait of the team: starting from the extraordinary human and scientific experience of via Panisperna, up to the patent negotiations in USA, to which Pontecorvo’s flight to URSS put an end with unexpected consequences; getting to his first return in Italy, allowed by the sovietic government in 1978, on the occasion of the conference celebrating Edoardo Amaldi’s 70th anniversary. That was the first of several encounters of the author of this paper with Bruno Pontecorvo, which are here briefly recounted, as minor episodes giving a personal perspective on the man. 1. – Fast neutrons, slow neutrons At the beginning of 1934, after reading the papers by Joliot and Curie reporting the discovery of artificial radioactivity produced by alfa particles, Enrico Fermi tried to create artificial radioisotopes irradiating many elements with neutrons. The neutrons were produced by a Poα + Be source, prepared by Franco Rasetti and similar to the one used by the Joliot-Curies. -
Chapter 1 High-Energy Astrophysical Neutrinos
July 9, 2018 21:42 ws-rv9x6 Book Title trisep_halzen_061918 page 1 Chapter 1 High-Energy Astrophysical Neutrinos Francis Halzen Wisconsin IceCube Particle Physics Center UW{Madison, Madison, WI USA [email protected] Chargeless, weakly-interacting neutrinos are ideal astronomical messen- gers because they travel through space without scattering, absorption, or deflection. They provide the only unobstructed view of cosmic accelera- tors. But this weak interaction also makes them notoriously difficult to detect, leading to neutrino observatories requiring large-scale detectors. The IceCube experiment discovered PeV-energy neutrinos originating beyond the Sun, with energies bracketed by those of TeV-energy gamma rays and EeV-energy extragalactic cosmic rays. In this chapter, we dis- cuss the IceCube neutrino telescope, the status of the observation of cosmic neutrinos, and what neutrinos can tell us about the nonthermal Universe. Besides the search for the sources of Galactic and extragalactic cosmic rays, the scientific missions of IceCube and similar instruments under construction in the Mediterranean Sea and Lake Baikal include the observation of Galactic supernova explosions, the search for dark matter, and the study of neutrinos themselves. 1 July 9, 2018 21:42 ws-rv9x6 Book Title trisep_halzen_061918 page 2 2 Francis Halzen Contents 1.
