Multi-Component Dark Matter as a Solution to the Galactic Center GeV Excess
Farinaldo S. Queiroz, Clarissa Siqueira, Carlos E. Yaguna
The Galactic Center Excess (GCE) is a compelling signature of dark matter annihilation, but its spectral morphology is difficult to reconcile with the traditional paradigm of a sin…
Singlet Dirac dark matter streamlined
Carlos E. Yaguna, Óscar Zapata
We propose a new and compact realization of singlet Dirac dark matter within the WIMP framework. Our model replaces the standard stabilizing symmetry with a , and uses s…
A minimal model of fermion FIMP dark matter
Carlos E. Yaguna, Óscar Zapata
We investigate a simple extension of the standard model (SM) in which the dark matter consists of a feebly interacting fermion (FIMP), charged under a new symmetry, that is p…
The model of three-component scalar dark matter
Geneviève Bélanger, Alexander Pukhov, Carlos E. Yaguna +1
We investigate, for the first time, a scenario where the dark matter consists of three complex scalar fields that are stabilized by a single symmetry. As an extension of the…
Fermion and scalar two-component dark matter from a symmetry
Carlos E. Yaguna, Óscar Zapata
We revisit a two-component dark matter model in which the dark matter particles are a singlet fermion () and a singlet scalar (), both stabilized by a single symmetry.…
Laboratory limits on the annihilation or decay of dark matter particles
Teresa Marrodán Undagoitia, Werner Rodejohann, Tim Wolf +1
Constraints on the indirect detection of dark matter are usually obtained from observations of astrophysical objects -- the Galactic Center, dwarf galaxies, M31, etc. Here we propo…
