VDM: a model for vector dark matter [PDF]
Journal of Cosmology and Astroparticle Physics, 2012 We construct a model based on a new $U(1)_X$ gauge symmetry and a discrete $Z_2$ symmetry under which the new gauge boson is odd. The model contains new complex scalars which carry $U(1)_X$ charge but are singlets of the Standard Model. The $U(1)_X$ symmetry is spontaneously broken but the $Z_2$ symmetry is maintained, making the new gauge boson a dark

Stringy dark energy model with cold dark matter
Physics Letters B, 2005 Cosmological consequences of adding the Cold Dark Matter (CDM) to the exactly solvable stringy Dark Energy (DE) model are investigated. The model is motivated by the consideration of our Universe as a slowly decaying D3-brane. The decay of this D-brane is described in the String Field Theory framework.

Lighting up the LHC with Dark Matter
Journal of High Energy Physics, 2023 We show that simultaneously explaining dark matter and the observed value of the muon’s magnetic dipole moment may lead to yet unexplored photon signals at the LHC.

Scalar simplified models for dark matter [PDF]
Physical Review D, 2015 We introduce a set of minimal simplified models for dark matter interactions with the Standard Model, connecting the two sectors via either a scalar or pseudoscalar particle. These models have a wider regime of validity for dark matter searches at the LHC than the effective field theory approach, while still allowing straightforward comparison to ...

Dark matter in inert triplet models [PDF]
Physical Review D, 2011 We study the inert triplet models, in which the standard model (SM) is extended to have a new SU(2)L triplet scalar (Y=0 or 2) with an Z2 symmetry. We show that the neutral component of the triplet can be a good dark matter candidate. In particular, for the hypercharge Y=0 triplet model, the WMAP data favors the region where the dark matter mass is ...

Model for neutrino masses and dark matter [PDF]
Physical Review D, 2003 We propose a model for neutrino masses that simultaneously results in a new dark matter candidate, the right-handed neutrino. We derive the dark matter abundance in this model, show how the hierarchy of neutrino masses is obtained, and verify that the model is compatible with existing experimental results.

Spintessence! New models for dark matter and dark energy
Physics Letters B, 2002 We investigate a class of models for dark matter and/or negative-pressure, dynamical dark energy consisting of ``spintessence,'' a complex scalar field $ϕ$ spinning in a U(1)-symmetric potential $V(ϕ)=V(|ϕ|)$. As the Universe expands, the field spirals slowly toward the origin.

Minimal model of gravitino dark matter [PDF]
Physical Review D, 2017 Motivated by the absence of signals of new physics in both searches for new particles at LHC and for a Weakly Interacting Massive Particle (WIMP) dark matter candidate, we consider a scenario where supersymmetry is broken at a scale above the reheating temperature.
