Autor: Mathieu Boudaud, Yoann Génolini, Laurent Derome, Julien Lavalle, David Maurin, Pierre Salati, Pasquale D. Serpico

Publikováno v: Physical Review Research, Vol 2, Iss 2, p 023022 (2020)

The Alpha Magnetic Spectrometer (AMS-02) experiment has ushered cosmic-ray physics into precision era. In an earlier paper [Génolini et al., Phys. Rev. D 99, 123028 (2019)10.1103/PhysRevD.99.123028], we designed an improved method to calibrate propa

Galactic charged cosmic rays (notably electrons, positrons, antiprotons and light antinuclei) are powerful probes of dark matter annihilation or decay, in particular for candidates heavier than a few MeV or tiny evaporating primordial black holes. Re

The vertical diffusive halo size of the Galaxy, $L$, is a key parameter for dark matter indirect searches. It can be better determined thanks to recent AMS-02 data. We set constraints on $L$ from Be/B and $^{10}$Be/Be data, and we performed a consist

The AMS-02 experiment measured several secondary-to-primary ratios enabling a detailed study of Galactic cosmic-ray transport. We constrain previously derived benchmark scenarios (based on AMS-02 B/C data only) using other secondary-to-primary ratios

Primordial black holes may have been produced in the early stages of the thermal history of the Universe after cosmic inflation. If so, dark matter in the form of elementary particles can be subsequently accreted around these objects, in particular w

Is the B/C slope in AMS-02 data actually telling us something about the diffusion coefficient slope?

Autor: M. Vecchi, L. Derome, P. I. Batista, Manuela Vecchi, Vivian Poulin, Pasquale D. Serpico, Mathieu Boudaud, Julien Lavalle, Pierre Salati, David Maurin, Yoann Génolini

Publikováno v: Proceedings of 36th International Cosmic Ray Conference — PoS(ICRC2019).

The measurement of the boron to carbon flux ratio provides relevant insights on the propagation of cosmic rays in the Galaxy. There is a common misconception about the fact that high-energy B/C data from AMS-02 directly provides the slope of the diff
