Empirical Models for Dark Matter Halos. I. Nonparametric Construction of Density Profiles and Comparison with Parametric Models [PDF]

, 2005
We use techniques from nonparametric function estimation theory to extract the density profiles, and their derivatives, from a set of N-body dark matter halos.

Minimal consistent Dark Matter models for systematic experimental characterisation: fermion Dark Matter

Journal of High Energy Physics, 2022
The search for a Dark Matter particle is the new grail and hard-sought nirvana of the particle physics community. From the theoretical side, it is the main challenge to provide a consistent and model-independent tool for comparing the bounds and reach of

Asymmetries in extended dark sectors: a cogenesis scenario

Journal of High Energy Physics, 2023
The observed dark matter relic abundance may be explained by different mechanisms, such as thermal freeze-out/freeze-in, with one or more symmetric/asymmetric components. In this work we investigate the role played by asymmetries in determining the yield

The Z 7 model of three-component scalar dark matter

Journal of High Energy Physics, 2023
We investigate, for the first time, a scenario where the dark matter consists of three complex scalar fields that are stabilized by a single Z 7 symmetry.

The continuum dark matter zoo

Journal of High Energy Physics, 2023
We generalize the recently proposed continuum dark matter model to the case where the dark matter consists of a spin-1/2 or spin-1 gapped continuum. We construct simple continuum analogs of weakly interacting massive particles annihilating through the Z ...

Global analyses of Higgs portal singlet dark matter models using GAMBIT [PDF]

The European Physical Journal C, 2018
We present global analyses of effective Higgs portal dark matter models in the frequentist and Bayesian statistical frameworks. Complementing earlier studies of the scalar Higgs portal, we use GAMBIT to determine the preferred mass and coupling ranges ...

Search for Invisible Axion Dark Matter in the 3.3-4.2  μeV Mass Range. [PDF]

Physical Review Letters, 2021
We report the results from a haloscope search for axion dark matter in the 3.3-4.2  μeV mass range. This search excludes the axion-photon coupling predicted by one of the benchmark models of "invisible" axion dark matter, the Kim-Shifman-Vainshtein ...

Xogenesis [PDF]

, 2011
We present a new paradigm for dark matter in which a dark matter asymmetry is established in the early universe that is then transferred to ordinary matter.

Constraining Dark Matter Models with a Light Mediator at the PandaX-II Experiment. [PDF]

Physical Review Letters, 2018
We search for nuclear recoil signals of dark matter models with a light mediator in PandaX-II, a direct detection experiment in the China Jinping underground laboratory.

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.
