Seesaw Cosmology
Nicolás Bernal, Chee Sheng Fong, Ãscar Zapata
The paper investigates a reheating scenario where the inflaton decays into right‑handed neutrinos that generate light neutrino masses via the type‑I seesaw, leading to a nonstandar…
Probing inelastic sub-GeV dark matter at the DUNE near detector
Amalia Betancur, Gustavo Castrillón, Gustavo Castrillón +2
We study inelastic dark matter (iDM) in a minimal and ultraviolet-complete framework in which the dark photon mass arises from a dark Higgs mechanism. The spontaneous breaking of a…
Feasibility to probe the dynamical scotogenic model at the LHC
Gustavo Ardila-Tafurth, Andrés Flórez, Cristian RodrÃguez +2
We perform a feasibility study to probe dark matter (DM) production at the LHC within a global scotogenic model. The study is conducted using the Markov Chain Monte Carlo…
Dark matter in QCD-like theories with a theta vacuum: cosmological and astrophysical implications
Camilo GarcÃa-Cely, Giacomo Landini, Ãscar Zapata
QCD-like theories in which the dark matter (DM) of the Universe is hypothesized to be a thermal relic in the form of a dark pion has been extensively investigated, with most studie…
Pion dark matter in a vacuum: a thermal relic with sharp velocity-dependent self-interactions
Camilo GarcÃa-Cely, Giacomo Landini, Luca Marsili +1
As recently proposed, a non-vanishing topological angle may play a central role in QCD-like theories of dark matter (DM). In this work, we introduce a dark photon portal to the Sta…
Probing low-reheating scenarios with minimal freeze-in dark matter
Nicolás Bernal, Chee Sheng Fong, Ãscar Zapata
The parameter space of freeze-in dark matter (DM) with mass through light dark photon (``minimal freeze-in DM'') is currently being probed by direct detection experiments th…
