Cosmological and astrophysical signatures of dark matter annihilations into pseudo-Goldstone bosons
Camilo Garcia-Cely, Alejandro Ibarra, Emiliano Molinaro
We investigate a model where the dark matter particle is a chiral fermion field charged under a global symmetry which is assumed to be spontaneously broken, leading to a pse…
Dark matter production from Goldstone boson interactions and implications for direct searches and dark radiation
Camilo Garcia-Cely, Alejandro Ibarra, Emiliano Molinaro
The stability of the dark matter particle could be attributed to the remnant symmetry that arises from the spontaneous breaking of a global U(1) symmetry. This plausible scen…
Simulating spin-3/2 particles at colliders
Neil D. Christensen, P. de Aquino, N. Deutschmann +7
Support for interactions of spin-3/2 particles is implemented in the FeynRules and ALOHA packages and tested with the MadGraph 5 and CalcHEP event generators in the context of thre…
Novel Gamma-ray Spectral Features in the Inert Doublet Model
Camilo Garcia-Cely, Alejandro Ibarra
The inert doublet model contains a neutral stable particle which is an excellent dark matter candidate. We discuss in this paper the indirect signatures of this model in gamma-rays…
