Probing Solar Heavy Neutrinos with Heliospheric Electrons
Marco Drewes, Jan Heisig, Valentin Weber
We search for an excess of electrons and positrons in the interplanetary space from the decays of heavy neutrinos produced in nuclear reactions in the Sun. Using measurements of th…
CosmiXs: Cosmic messenger spectra for indirect dark matter searches
Chiara Arina, Mattia Di Mauro, Nicolao Fornengo +3
The energy spectra of particles produced from dark matter (DM) annihilation or decay are one of the fundamental ingredients to calculate the predicted fluxes of cosmic rays and rad…
Revisiting the AMS-02 antiproton excess: The role of correlated errors
Jan Heisig, Michael Korsmeier, Martin Wolfgang Winkler
Cosmic-ray antiprotons are a remarkable diagnostic tool for the study of astroparticle physics' processes in our Galaxy. While the bulk of measured antiprotons is consistent with a…
Cosmic-ray antiprotons in the AMS-02 era: A sensitive probe of dark matter
Jan Heisig
Cosmic-ray antiprotons are a powerful tool for astroparticle physics. While the bulk of measured antiprotons is consistent with a secondary origin, the precise data of the AMS-02 e…
Dark matter or correlated errors: Systematics of the AMS-02 antiproton excess
Jan Heisig, Michael Korsmeier, Martin Wolfgang Winkler
Several studies have pointed out an excess in the AMS-02 antiproton spectrum at rigidities of 10-20 GV. Its spectral properties were found to be consistent with a dark-matter parti…
Scrutinizing the evidence for dark matter in cosmic-ray antiprotons
Alessandro Cuoco, Jan Heisig, Lukas Klamt +2
Global fits of primary and secondary cosmic-ray (CR) fluxes measured by AMS-02 have great potential to study CR propagation models and search for exotic sources of antimatter such…
