The NMSSM with F-theory unified boundary conditions (2013)
Journal Article

We study the phenomenological viability of a constrained NMSSM with parameters subject to unified boundary conditions from F-theory GUTs. We find that very simple assumptions about modulus dominance SUSY breaking in F-theory unification lead to a pre... Read More about The NMSSM with F-theory unified boundary conditions.

Nuclear uncertainties in the spin-dependent structure functions for direct dark matter detection (2013)
Journal Article

We study the effect that uncertainties in the nuclear spin-dependent structure functions have in the determination of the dark matter (DM) parameters in a direct detection experiment. We show that different nuclear models that describe the spin-depen... Read More about Nuclear uncertainties in the spin-dependent structure functions for direct dark matter detection.

A 119-125 GeV Higgs from a string derived slice of the CMSSM (2012)
Journal Article

The recent experimental hints for a relatively heavy Higgs with a mass in the range 119-125 GeV favour supersymmetric scenarios with a large mixing in the stop mass matrix. It has been shown that this is possible in the constrained Minimal Super-symm... Read More about A 119-125 GeV Higgs from a string derived slice of the CMSSM.

Even if supersymmetric particles are found at the Large Hadron Collider (LHC), it will be difficult to prove that they constitute the bulk of the dark matter (DM) in the Universe using LHC data alone. We study the complementarity of LHC and DM indire... Read More about Complementarity of indirect and accelerator dark matter searches.

Very light right-handed (RH) sneutrinos in the Next-to-Minimal Supersymmetric Standard Model can be viable candidates for cold dark matter. We investigate the prospects for their direct detection, addressing their compatibility with the recent signal... Read More about Very light right-handed sneutrino dark matter in the NMSSM.
