2HDM singlet portal to dark matter
M. E. Cabrera, J. A. Casas, A. Delgado +1
Higgs portal models are the most minimal way to explain the relic abundance of the Universe. They add just a singlet that only couples to the Higgs through a single parameter that…
Generalized Blind Spots for Dark Matter Direct Detection in the 2HDM
M. E. Cabrera, J. A. Casas, A. Delgado +1
In this paper we study the presence of generalized blind spots, i.e. regions of the parameter space where the spin-independent cross section for dark matter direct detection is sup…
Revealing mass-degenerate states in Higgs boson signals
Shehu AbdusSalam, Maria Eugenia Cabrera
The observed Higgs boson signals to-date could be due to having two quasi-degenerate 125 GeV scalar states in Nature. This kind of scenario tallies well with the predictions from t…
Naturalness of MSSM dark matter
Maria Eugenia Cabrera, J. Alberto Casas, Antonio Delgado +2
There exists a vast literature examining the electroweak (EW) fine-tuning problem in supersymmetric scenarios, but little concerned with the dark matter (DM) one, which should be c…
LHC and dark matter phenomenology of the NUGHM
Maria Eugenia Cabrera, Alberto Casas, Roberto Ruiz de Austri +1
We present a Bayesian analysis of the NUGHM, a supersymmetric scenario with non-universal gaugino masses and Higgs masses, including all the relevant experimental observables and d…
Multi-lepton signatures at LHC from sneutrino dark matter
Chiara Arina, Maria Eugenia Cabrera
We investigate multi-lepton LHC signals arising from an extension at the grand unification scale of the standard minimal supersymmetric model (MSSM) involving right-handed neutrino…
