The minimal extension of the MSSM (NMSSM) has been widely studied in the search for a natural solution to
the $\mu$ problem. In this work, we consider a variation of the NMSSM where an extra singlet is added and a Peccei-Quinn symmetry is imposed. We study its neutralino sector and compute the annihilation of the lightest neutralino. We use existent cosmological and collider data to constrain...

Last year saw the discovery of a Higgs boson at the LHC, with mass around 125 GeV, as well as a potential signal of dark matter annihilation in the Fermi-LAT data coming from the Galactic Center: a mono-chromatic gamma-ray line peaked at around 130 GeV. Both are difficult to explain in minimal supersymmetric models, but can be readily accommodated in the Next-to-MSSM (NMSSM). In this talk, I...

We present a novel new way of introducing scalar dark matter to Little Higgs Models without the need for T-Parity. Presented is a general technique that can be introduced to existing models, and then show the results for modifications to the Littlest Higgs model.

Though the discovery of a 125 GeV candidate Higgs boson resolves the origin of electroweak symmetry breaking, questions remain regarding physics beyond the Standard Model, the energy scale associated with new physics, and the nature of dark matter. I will discuss several extensions of the Standard Model that address these questions. The question arises whether or not the very minimum of the...

We investigate a simple model where Lepton number (L) is promoted to a local $U(1)_L$ gauge symmetry which is then spontaneously broken leading to a viable thermal DM candidate and vector-like leptons as a byproduct. The dark matter arises as part of the exotic lepton sector required by the need to satisfy anomaly cancellation and is a Dirac electroweak (mostly) singlet neutrino. It is...
