Cosmic-ray Antinuclei as Messengers of New Physics: Status and Outlook for the New Decade
P. von Doetinchem, K. Perez, T. Aramaki +59
The precise measurement of cosmic-ray antinuclei serves as an important means for identifying the nature of dark matter and other new astrophysical phenomena, and could be used wit…
Cosmic-ray transport from AMS-02 B/C data: benchmark models and interpretation
Yoann Genolini, Mathieu Boudaud, Pedro Ivo Batista +11
This article aims at establishing new benchmark scenarios for Galactic cosmic-ray propagation in the GV-TV rigidity range, based on fits to the AMS-02 B/C data with the USINE v3.5…
Where do the AMS-02 anti-helium events come from?
Vivian Poulin, Pierre Salati, Ilias Cholis +2
We discuss the origin of the anti-helium-3 and -4 events possibly detected by AMS-02. Using up-to-date semi-analytical tools, we show that spallation from primary hydrogen and heli…
Indications for a high-rigidity break in the cosmic-ray diffusion coefficient
Yoann Genolini, Pasquale D. Serpico, Mathieu Boudaud +9
Using cosmic-ray boron to carbon ratio (B/C) data recently released by the AMS-02 experiment, we find tantalizing indications ({\it decisive evidence}, in Bayesian terms) in favor…
The pinching method for Galactic cosmic ray positrons: implications in the light of precision measurements
M. Boudaud, E. F. Bueno, S. Caroff +7
Two years ago, the AMS collaboration released the most precise measurement of the cosmic ray positron flux. It confirms that pure secondary predictions fall below the data above 10…
A new look at the cosmic ray positron fraction
Mathieu Boudaud
The positron fraction in cosmic rays was found to be steadily increasing in function of energy, above 10 GeV. This behaviour contradicts standard astrophysical mechanisms, in…
