Brazilian Community Report on Dark Matter
E. Abdalla, I. F. M. Albuquerque, A. Alves +52
This white paper summarizes the activities of the Brazilian community concerning dark matter physics and highlights the importance of financial support to Brazilian groups that are…
Explaining the AMS positron excess via Right-handed Neutrinos
Farinaldo S. Queiroz, Clarissa Siqueira
We have witnessed in the past decade the observation of a puzzling cosmic-ray excess at energies larger than GeV. The AMS-02 data published this year has new ingredients such…
Has AMS-02 Observed Two-Component Dark Matter?
Stefano Profumo, Farinaldo Queiroz, Clarissa Siqueira
There is convincing observational evidence for an increasing cosmic-ray positron-to-electron ratio at energies larger than ~GeV, at odds with expectations from secondary p…
Secluded Dark Matter in light of the Cherenkov Telescope Array (CTA)
Clarissa Siqueira
Secluded dark matter is one of the most popular dark matter models, where dark matter annihilations go into particles that belong to a dark sector. An interesting way to probe such…
Search for Semi-Annihilating Dark Matter with Fermi-LAT, H.E.S.S., Planck, and the Cherenkov Telescope Array
Farinaldo S. Queiroz, Clarissa Siqueira
Dark matter annihilations have been fiercely restricted by the non-observation of excess events in indirect detection probes. Typically the interactions that dictate annihilation a…
