Dark Matter in SUGRA, Strings and Branes [PDF]
, 2006 A brief review is given of dark matter in SUGRA, strings and branes. For SUGRA models the implications of Yukawa coupling unification on dark matter are discussed in the light of $g-2$ and $b\to s\gamma$ constraints.

The Dawn of FIMP Dark Matter: A Review of Models and Constraints [PDF]
, 2017 We present an overview of scenarios where the observed Dark Matter (DM) abundance consists of Feebly Interacting Massive Particles (FIMPs), produced nonthermally by the so-called freeze-in mechanism.

Multi-Component Dark Matter [PDF]
, 2008 We explore multi-component dark matter models where the dark sector consists of multiple stable states with different mass scales, and dark forces coupling these states further enrich the dynamics.

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

Light dark matter: Models and constraints [PDF]
, 2017 We study the direct detection prospects for a representative set of simplified models of sub-GeV dark matter (DM), accounting for existing terrestrial, astrophysical and cosmological constraints.

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.

The Astronomy and Astrophysics Review, 2020 Ultra-light dark matter is a class of dark matter models (DM), where DM is composed by bosons with masses ranging from $$10^{-24}\, \mathrm {eV}< m < \mathrm {eV}$$ 10 - 24 eV < m < eV . These models have been receiving a lot of attention in the past few

Unification of Gauge Couplings in Radiative Neutrino Mass Models [PDF]
, 2016 We investigate the possibility of gauge coupling unification in various radiative neutrino mass models, which generate neutrino masses at one- and/or two-loop level.

Black holes and gravitational waves in models of minicharged dark matter [PDF]
Journal of Cosmology and Astroparticle Physics, 2016 In viable models of minicharged dark matter, astrophysical black holes might be charged under a hidden U(1) symmetry and are formally described by the same Kerr-Newman solution of Einstein-Maxwell theory.

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.
