Constraining Effective Field Theories for dark matter candidates annihilating into gamma-ray lines with CTAO
Lucia Angel, Debasish Borah, Jacinto P. Neto +2
Gamma-ray lines constitute a smoking gun signature for annihilating dark matter particles. Imaging Atmospheric Cherenkov Telescopes and satellites have searched for such signals bu…
Type-II Seesaw Mechanism for Dirac Neutrinos and its Implications on and Lepton Flavor Violation in a 3-3-1 model
Vinícius Oliveira, Patricio Escalona, Lucia Angel +2
In this study, we implement the type-II seesaw mechanism for Dirac neutrino masses within the framework of a 3-3-1 model. To this end, we introduce a scalar sextet and impose both…
Updated BBN Bounds on Hadronic Injection in the Early Universe: The Gravitino Problem
Lucia Angel, Giorgio Arcadi, Matheus M. A. Paixão +1
Late-decaying particles naturally arise in many extensions of the Standard Model, directly impacting key cosmological processes in the early universe, such as Big Bang Nucleosynthe…
Dark Matter Line Searches with the Cherenkov Telescope Array
S. Abe, J. Abhir, A. Abhishek +562
Monochromatic gamma-ray signals constitute a potential smoking gun signature for annihilating or decaying dark matter particles that could relatively easily be distinguished from a…
Constraining Gamma-ray Lines from Dark Matter Annihilation using Fermi-LAT and H.E.S.S. data
Lucia Angel, Guillermo Gambini, Leticia Guedes +2
Using 14 years of Fermi-LAT data and 10 years of H.E.S.S. observations in the direction of the galactic center, we derive limits on gamma-ray lines originated from dark matter anni…
