The Telescope Array is the largest cosmic ray observatory in the northern hemisphere. Ultra high energy cosmic rays are observed indirectly via the extensive air shower they induce when they collide with a nucleus in the upper atmosphere. A large array of scintillator detectors is spread over ~1800 sq km in the west desert of Utah, USA to sample the footprint of the showers when they arrive...
The High-Altitude Water Cherenkov (HAWC) gamma-ray Observatory is an extensive air shower array consisting of 300 Water Cherenkov detectors located at 4100 m in Puebla, Mexico. With a wide field-of-view of ~2 sr, operating 24 hrs/day with a high duty cycle (> 95%), it is the perfect instrument to perform all-sky monitoring. HAWC has been surveying the gamma-ray sky since 2015 and has improved...
The Tibet Air Shower (AS) array and the underground water-Cherenkov-type muon detector (MD) array have been operating successfully since 2014 at an altitude of 4,300 m in Tibet, China. The primary energy and arrival direction are determined by the surface AS array, while the MD array enables us to drastically reject background cosmic rays by counting the number of muons in an air shower. In...
The IceCube Neutrino Observatory detects particles produced from cosmic rays and neutrinos to explore the high-energy universe. The deep in-ice array consists of 5160 light sensors instrumenting a cubic kilometer of South Pole ice at depths between 1.5 and 2.5 kilometers measuring high-energy neutrino interactions and PeV muon bundles from cosmic ray air showers. The deep detector is...
In 2019 the Tibet ASฮณ collaboration reported the detection of sub-PeV $\gamma$-rays coming from the Crab nebula using a novel technique with a hybrid Surface Array and underground water Cherenkov muon detector to discriminate against hadrons. Using this technique, we are now building a new experiment to explore the gamma-ray sky in the Southern Hemisphere looking for the origins of cosmic rays...
In this talk, recent measurements of distributions sensitive to the underlying event, the hadronic activity observed in relationship with the hard scattering in the event, by the ATLAS experiment are presented. Underlying event observables like the average particle multiplicity and the transverse momentum sum are measured for Kaons as Lambda baryons as a function of the leading track-jet and...
The LHCf experiment measures neutral particles, such as photons and neutrons, emitted in the very forward region of LHC collisions. These energetic particles play an important role in the air shower development induced by very high energy cosmic-rays. In September 2022, we performed data taking with proton-proton at \sqrt{s} = 13.6 TeV and 300 M events were recorded, which is about 10 times...
This talk will explore key highlights from the ALICE experiment at CERN's Large Hadron Collider (LHC) and its connection to cosmic ray physics.
High-energy collisions at the high-luminosity Large Hadron Collider (HL-LHC) will produce an enormous flux of particles along the beam collision axis that is not accessible by existing LHC experiments. Multi-particle production in the far-forward region is of particular interest for astroparticle physics. High-energy cosmic rays produce extensive air showers (EAS) in the atmosphere which are...
The muon content of extensive air showers is not only important for the study of the elemental composition of cosmic rays, but also serves as a test and validation of modern high-energy hadronic interaction models at laboratory energies well above 1 PeV. This line of research has led to the discovery of several discrepancies between the model predictions and the measurements on the muon...
In this contribution we will present final results on production spectra in pion-carbon interactions, which are of fundamental importance to improve the extensive air shower modeling, and hence the interpretation of ultra-high-energy-cosmic-rays measurements. In particular, our measurements of (anti)baryons and $\rho^0$ production in pion-carbon interactions will contribute to improve the...
The complementary information carried by cosmic rays, photons, neutrinos, and gravitational waves provides extremely valuable insights about individual cosmic sources and source populations. The Pierre Auger Observatory plays a central role in multi-messenger astronomy, and its results provide a deeper view of the properties of ultra-high cosmic rays. In this talk, we will review some of the...
"The Hyper-Kamiokande (HK) experiment, a next-generation water-Cherenkov neutrino
detector near Toyama, Japan, aims to significantly advance our understanding of neutrino
physics. The specific physics goals include studying neutrino oscillations to refine their
parameters, observing asymmetries between neutrino and antineutrino oscillations to
investigate CP violation, probing Grand...
CORSIKA 8 is a completely rewritten Monte-Carlo simulation for cascades in cosmic-ray physics. The aim is to provide a flexible framework, written in modern C++, that can be adapted to applications beyond air-showers. This allows to use of the software in scenarios that were previously difficult or impossible to simulate in CORSIKA 7. This includes, for example, cascades that cross from air...
Results of the QGSJET-III Monte Carlo generator, regarding calculated characteristics of extensive air showers (EAS) initiated by very high energy cosmic rays, are presented in comparison to the corresponding predictions of other cosmic ray interaction models. A quantitative analysis of uncertainties for such predictions is performed, notably, regarding possibilities to enhance the EAS muon...
