Dark Matter in the General 2HDM with Extra Top Yukawa Couplings
Leon M. G. de la Vega, Mohamed Krab
We extend the general two Higgs doublet model (G2HDM), which introduces extra Yukawa couplings, by an additional real scalar singlet (G2HDM+S), providing a viable scalar dark matte…
Dark matter for Majorana neutrinos in a symmetry
Leon M. G. de la Vega, Patrick J. Fitzpatrick, Rolando Martinez-Ramirez +1
In the minimal Scotogenic model with fermionic dark matter, the neutrino Yukawa matrix is fine-tuned to satisfy current bounds on while producing dark matter thr…
The solution to the IceCube Ultra High Energy neutrino deficit in light of NA64
Leon M. G. de la Vega, Eduardo Peinado, Jose Wudka
In this work we analyze the scenario where a MeV scale gauge boson can explain the deficit in the diffuse ultra high energy (UHE) astrophysical neutrino spectrum observe…
Closing the dark photon window to thermal dark matter
Leon M. G. de la Vega, R. Ferro-Hernandez, A. García-Viltres +2
The nature of dark matter remains a central question in particle physics, cosmology, and astrophysics. The prevailing hypothesis postulates that dark matter consists of particles t…
Neutrino masses and self-interacting dark matter with mass mixing gauge portal
Leon M. G. de la Vega, Eduardo Peinado, Jose Wudka
New light gauge bosons can affect several low-energy experiments, such as atomic parity violation or colliders. Here, we explore the possibility that a dark sector is charged under…
Complementarity between dark matter direct searches and CENS experiments in models
Leon M. G. de la Vega, L. J. Flores, Newton Nath +1
We explore the possibility of having a fermionic dark matter candidate within models for CENS experiments in light of the latest COHERENT data and the current and future…
Simple A4 models for dark matter stability with texture zeros
Leon M. G. de la Vega, R. Ferro-Hernandez, E. Peinado
In a simple framework which naturally incorporates dark matter stability and neutrino phenomenology, we compute all the possible texture zeros which arise when the non-abelian flav…
