SUSY-QCD corrected and Sommerfeld enhanced stau annihilation into heavy quarks with scheme and scale uncertainties

We investigate stau-antistau annihilation into heavy quarks in the phenomenological Minimal Supersymmetric Standard Model within the \DMNLO project. Expand abstract.

Dark Matter Mass and Anisotropy in Directional Detector

Directional direct detection of dark matter is expected to be a hopeful way to discriminate isotropic distribution from anisotropic one. Expand abstract.

Towards A UV-Model of Kinetic Mixing and Portal Matter

The nature of dark matter (DM) and how it might interact with the particles of the Standard Model (SM) is an ever-growing mystery. Expand abstract.

Direct detection and complementary constraints for sub-GeV dark matter

Finally we stress that dark matter self-interactions place stringent limits independently of the dark matter production mechanism. Expand abstract.

LHC phenomenology with hidden sector dark matter: a long-lived stau and heavy Higgs in an observable range

The presence of a hidden sector with very weak interactions with the standard model has significant implications on LHC signatures. Expand abstract.

A radiative seesaw model with GeV singlet-doublet fermion and TeV triplet scalar dark matter

By extending the Standard Model with singlet-doublet fermions and triplet scalars, all odd under a new $Z_2$ symmetry, we introduce a radiative seesaw model that can simultaneously account for dark matter, explain the existence of neutrino masses and allow for gauge coupling unification.

Can EDGES observation favour any dark matter model?

We show that all these dark matter models cannot be statistically distinguished using the available EDGES data. Expand abstract.

Neural physical engines for inferring the halo mass distribution function

As a result, we are able to sample the initial phases of the dark matter density field whilst inferring the parameters describing the halo mass distribution function, providing a fully Bayesian interpretation of both the initial dark matter density distribution and the neural bias model.

Dynamical Friction in a Fuzzy Dark Matter Universe

We present an in-depth exploration of the phenomenon of dynamical friction in a universe where the dark matter is composed entirely of so-called Fuzzy Dark Matter (FDM), ultralight bosons of mass $m\sim\mathcal{O}(10^{-22})\,$eV. Expand abstract.

A theory for scotogenic dark matter stabilised by residual gauge symmetry

Dark matter stability can result from a residual matter-parity symmetry, following naturally from the spontaneous breaking of the gauge symmetry. Expand abstract.
