Novel constraints on the particle nature of dark matter from stellar streams [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 Tidal streams are highly sensitive to perturbations from passing dark matter (DM) subhalos and thus provide a means of measuring their abundance. In a recent paper, we analyzed the distribution of stars along the GD-1 stream with a combination of data from the Gaia satellite and the Pan-STARRS survey, and we demonstrated that the population of DM ...

Two natural scenarios for dark matter particles coexisting with supersymmetry [PDF]
Modern Physics Letters A, 2019 We describe two natural scenarios in which both dark matter, weakly interacting massive particles (WIMPs) and a variety of supersymmetric partners should be discovered in the foreseeable future. In the first scenario, the WIMPs are neutralinos, but they are only one component of the dark matter, which is dominantly composed of other relic particles ...

IceCube at the frontier of macroscopic dark matter direct detection
Journal of High Energy Physics, 2022 For a class of macroscopic dark matter models, inelastic scattering of dark matter off a nucleus can generate electromagnetic signatures with GeV-scale energy.

Dark magnetic dipole property in fermionic absorption by nucleus and electrons
Journal of High Energy Physics, 2022 The fermionic dark matter (DM) absorption by nucleus or electron targets provides a distinctive signal to search for sub-GeV DM. We consider a Dirac fermion DM charged under a dark gauge group and with the dark magnetic dipole operator.

Multi-component dark sectors: symmetries, asymmetries and conversions
Journal of High Energy Physics, 2022 We study the relic abundance of several stable particles from a generic dark sector, including the possible presence of dark asymmetries. After discussing the different possibilities for stabilising multi-component dark matter, we analyse the final relic

Gamma-ray lines may reveal the CP nature of the dark matter particle [PDF]
Journal of Cosmology and Astroparticle Physics, 2019 Determining the fundamental properties of the dark matter is one of the most important open problems in particle physics today. If the dark matter particle has spin zero, one of these properties is its CP nature. That is, whether it is CP-even (scalar), CP-odd (pseudoscalar), or if its interactions violate CP.

Associated production of neutrino and dark fermion at future lepton colliders
Journal of High Energy Physics, 2023 Fermionic dark matter can be pairly produced and hence searched with missing energy at colliders. We extend such probe to the associated production of a neutrino and a dark sector fermion at the future e + e − colliders such as CEPC, FCC-ee, ILC, and ...

Natural Dark Matter from an unnatural Higgs boson and new colored particles at the TeV scale [PDF]
Journal of High Energy Physics, 2007 The thermal relic abundance of Dark Matter motivates the existence of new electroweak scale particles, independent of naturalness considerations. However, most unnatural Dark Matter models do not ensure the presence of new particles charged under SU(3)_C, resulting in challenging LHC phenomenology.
