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…
