Predicting the baryon asymmetry with degenerate right-handed neutrinos
S. Sandner, P. Hernandez, J. Lopez-Pavon +1
We consider the generation of a baryon asymmetry in an extension of the Standard Model with two singlet Majorana fermions that are degenerate above the electroweak phase transition…
Bounds on right-handed neutrino parameters from observable leptogenesis
Pilar Hernandez, Jacobo Lopez-Pavon, Nuria Rius +1
We revisit the generation of a matter-antimatter asymmetry in the minimal extension of the Standard Model with two singlet heavy neutral leptons (HNL) that can explain neutrino mas…
FIMP Dark Matter in Clockwork/Linear Dilaton Extra-Dimensions
Nicolás Bernal, Andrea Donini, Miguel G. Folgado +1
We study the possibility that Dark Matter (DM) is made of Feebly Interacting Massive Particles (FIMP) interacting just gravitationally with the Standard Model particles in the fram…
Relaxing Cosmological Neutrino Mass Bounds with Unstable Neutrinos
Miguel Escudero, Jacobo Lopez-Pavon, Nuria Rius +1
At present, cosmological observations set the most stringent bound on the neutrino mass scale. Within the standard cosmological model (CDM), the Planck collaboration reports $\s…
Spin-dependence of Gravity-mediated Dark Matter in Warped Extra-Dimensions
Miguel G. Folgado, Andrea Donini, Nuria Rius
We study the spin-dependence of Dark Matter (DM) particles which interact gravitationally with the Standard Model (SM) in an extra-dimensional Randall-Sundrum scenario. We assume t…
Kaluza-Klein FIMP Dark Matter in Warped Extra-Dimensions
Nicolás Bernal, Andrea Donini, Miguel G. Folgado +1
We study for the first time the case in which Dark Matter (DM) is made of Feebly Interacting Massive Particles (FIMP) interacting just gravitationally with the standard model parti…
