Toward universal coalescence models for antideuteron production
Mattia di Mauro, Jordan Koechler, Lorenzo Stefanuto +3
Cosmic-ray (CR) antinuclei, especially antideuteron and antihelium-3 nuclei , are among the most promising messengers for indirect dark ma…
Early-universe constraints on the electron mass
Michela Garramone, Stefano Gariazzo, Nicolao Fornengo
We investigate the impact of a nonstandard electron mass on early-Universe thermal history, focusing on neutrino decoupling and Big Bang Nucleosynthesis (BBN). In the standar…
Enhanced Cosmic-Ray Antinuclei Fluxes with Dark Matter Annihilation into SUEPs
Mattia Di Mauro, Caleb Gemmell, Austin Batz +4
Standard-Model (SM) hadronic parton showers initiated by secondary cosmic-ray production or dark matter (DM) annihilations robustly predict very low antinuclei yields and a strong…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Putting all the X in one basket: Updated X-ray constraints on sub-GeV Dark Matter
Marco Cirelli, Nicolao Fornengo, Jordan Koechler +2
Sub-GeV dark matter particles can annihilate or decay producing e^\pm pairs which upscatter the low-energy photon fields in the Galaxy and generate an X-ray emission (via the Inver…
CosmiXs: Improved spectra for dark matter indirect detection
Chiara Arina, Mattia Di Mauro, Nicolao Fornengo +3
The spectra of stable particles produced from dark matter (DM) are one of the most important ingredients to calculate the fluxes for DM indirect detection experiments. At energies…
