    16/10/2024, 14:45

    The origin of dark matter remains one of the most puzzling open problems in physics. Understanding its particle nature is a central focus of theoretical research and a primary objective for several experimental efforts. Among the various strategies for dark matter detection, indirect detection stands out as one of the most promising. This approach seeks to identify signals in flux data of the...

    16/10/2024, 15:40

    The CALorimetric Electron Telescope (CALET) is a high-energy cosmic-ray detector that has been in continuous operation on the International Space Station (ISS) since October 2015. Developed by JAXA in collaboration with ASI and NASA to study the origin of cosmic rays (CR), their acceleration and propagation mechanisms in the Galaxy, and to search for dark matter and the presence of potential...

  7. 5. Measuring the inelastic cross section of proton and helium-4 in space with DAMPE [10'+5']
    Paul Coppin (Universite de Geneve (CH))
    16/10/2024, 16:35

    The Dark Matter Particle Explorer (DAMPE) is an ongoing space-borne experiment for the direct detection of cosmic rays (CR). Thanks to its large geometric acceptance and thick calorimeter, DAMPE is able to detect CR ions up to unprecedented energies of hundreds of TeV. Following by now more than 8 years of successful operation, DAMPE has amassed a large dataset of high-energy hadronic...

  8. 10. Ultra-heavy nuclei and ultra-high-energy cosmic rays [10'+5']
    Prof. Denise Boncioli (University of L'Aquila)
    16/10/2024, 16:50

    Thanks to the experimental advancements in the field of ultra-high-energy cosmic rays (UHECRs), recent results about their mass composition indicate that, as the energy increases, the mean mass of these nuclei first decreases, reaching its lightest point around 2 EeV, and then afterward, increases significantly.

    These results motivated several studies for modelling the interactions...

  9. 12. Measurement of the proton-proton cross section at ultra-high energies with the Pierre Auger Observatory [10'+5']
    Dr Olena Tkachenko (Institute of Physics of the Czech Academy of Sciences)
    16/10/2024, 17:05

    The energies of cosmic rays significantly exceed the range of the existing human-made particle accelerators. The analysis of the air shower data makes it possible to infer the particle production cross sections - one of the most fundamental properties of soft QCD interactions at the highest energies. The depth at which the number of particles in a shower reaches its maximum is linked to the...

  10. 52. Photonuclear cross sections and UHECR transport: towards more transparency [10'+5']
    Leonel Morejon (Wuppertal University)
    16/10/2024, 17:20

    Studies of the origin and composition of ultra-high-energy cosmic rays involve simulating their interactions, predominantly with surrounding photon fields and involving photonuclear cross sections in the MeV-GeV range. Although such interactions within the source and during extra-galactic propagation are analogous, these scenarios are addressed separately and the codes employed for each of...

  14. 26. Desired reactions for nuclear production XS [15'+10']
    David Alain Maurin (Centre National de la Recherche Scientifique (FR))
    17/10/2024, 10:05

    High-precision cosmic-ray data from ongoing and recent past experiments are being released in the tens of the MeV/n to multi-TeV/n energy range. Astrophysical and dark matter interpretations of these data are limited by the precision of nuclear production cross sections. I will present the procedure we developed to rank nuclear reactions, whose measurements would be a game changer for the...

  15. 27. Production cross sections of electron, positrons and gamma rays [15'+10']
    Luca Orusa (University of Torino)
    17/10/2024, 10:30

    Accurate interpretation of cosmic-ray electron and positron fluxes, as well as gamma-ray emissions, requires precise knowledge of the cross sections governing cosmic-ray interactions with the interstellar medium. Primarily involving protons and helium, these reactions produce secondary positrons and gamma rays, key observables for probing cosmic-ray propagation, dark matter searches, and the...

    18/10/2024, 09:50

    The AMS collaboration has published recent results on deuteron-over-helium-4 ($d$/$^4$He) and helium-3-over-helium-4 ($^3$He/$^4$He) cosmic rays flux ratios with unprecedented precision and covering a wider energy range than previous experiments. Both $d$/$^4$He and $^3$He/$^4$He ratios are important to understand the propagation of cosmic rays in the Galaxy and the heliosphere, complementing...

    Priyarshini Ghosh (NASA Goddard Space Flight Center)
    18/10/2024, 10:05

    TIGERISS, the recently selected Pioneers mission, will look at elemental abundances across a wide Z range, from 5B up to 82Pb, for the first time with a single instrument, to further our knowledge of the way the galaxy redistributes elements. However, accurate cross section data is paramount to the accurate interpretation of this observed experimental data. High Z (>Z) proton spallation...

  31. 9. The Fluka cross sections for secondary cosmic rays: Latest results [10'+5']
    Pedro De la Torre Luque (Institute of theoretical physics (IFT-UAM))
    18/10/2024, 10:20

    Despite the simplicity of our phenomenological models of CR propagation, we have been able to explain with very good accuracy the fluxes of the main secondary CRs, including antiprotons. In this talk, we show new cross sections of CR interactions in the Galaxy computed with FLUKA, covering from light secondaries, such as deuterium, tritium or 3He, to gamma rays and neutrinos. In addition, we...

    Alessandro Cuoco
    18/10/2024, 10:35

    The AMS-02 experiment has provided high-precision measurements of several cosmic-ray (CR) species. We exploit the AMS-02 data to investigate CR propagation in the Galaxy, and provide updated constraints on reacceleration, convection, and the spatial and rigidity dependence of the diffusion coefficient. We explicitly consider the impact of the uncertainties in the nuclear production...

  33. 50. From the AMS-02 isotope fluxes to their production cross sections [10'+5']
    Meng-Jie Zhao (Key Laboratory of Particle Astrophysics, Institute of High Energy Physics, Chinese Academy of Sciences)
    18/10/2024, 10:50

    The AMS-02 collaboration has reported preliminary results on beryllium and lithium isotope fluxes, extending the energy range beyond that of previous experiments. As secondary CRs, the Be isotopes include both stable and unstable species, which are crucial for constraining the propagation parameters of the Galactic CRs. The $\rm^{10}Be/^9Be$ ratio measured by AMS-02 can better resolve the...

  37. 3. Antinucleon-nucleus interactions with the INCL code
    Jean-Christophe David

    The INCL intranuclear cascade code has been developed and used for a long time. Its aim is to simulate the interactions of light projectiles with all types of nuclei in an energy range from a few tens of MeV to 10-20 GeV. To do this, it has to be combined with a de-excitation code, and most of the time it is the ABLA code that is used. Both codes are also available in the Geant4 particle...
