WIMP Freeze-out dynamics under Tsallis statistics
Matias P. Gonzalez, Roberto A. Lineros
We generalize thermal WIMP (Weakly Interacting Massive Particle) freeze-out within Tsallis nonextensive statistics. Using Curado-Tsallis -distributions we compute $…
From WIMPs to FIMPs: Impact of Early Matter Domination
Javier Silva-Malpartida, Nicolás Bernal, Joel Jones-Pérez +1
In the context of non-standard cosmologies, an early matter-dominated (EMD) era can significantly alter the conventional dark matter (DM) genesis. In this work, we reexamine the im…
From WIMPs to FIMPs with Low Reheating Temperatures
Javier Silva-Malpartida, Nicolás Bernal, Joel Jones-Pérez +1
Weakly- and Feebly-Interacting Massive Particles (WIMPs and FIMPs) are among the best-motivated dark matter (DM) candidates. In this paper, we investigate the production of DM thro…
Dark Matter candidates in a Type-II radiative neutrino mass model
Roberto A. Lineros, Mathias Pierre
We explore the connection between Dark Matter and neutrinos in a model inspired by radiative Type-II seessaw and scotogenic scenarios. In our model, we introduce new electroweakly…
Fermion Dark Matter and Radiative Neutrino Masses from Spontaneous Lepton Number Breaking
Cesar Bonilla, Leon M. G. de la Vega, J. M. Lamprea +2
In this paper, we study the viability of having a fermion Dark Matter particle below the TeV mass scale in connection to the neutrino mass generation mechanism. The simplest realiz…
Neutrino oscillations in the galactic dark matter halo
R. A. Lineros
The observation of PeV neutrinos is an open window to study New Physics processes. Among all possible neutrino observables, the neutrino flavor composition can reveal underlying in…
