Experimental Approaches

AbstractSeveral experimental approaches are being utilised for the direct detection of the hypothetical weakly interacting massive particle which may constitute the majority of the non-luminous component of the Galaxy. These experimental techniques exploit the coherent recoil of target nuclei during an interaction and include thermal, ionisation, scintillation and tracking detectors. The challenges associated with this detection, the techniques employed and the current status of these searches are reviewed.

Modern Physics

Dark matter is an abundant component of our Universe and its detection and identification constitutes one of the most challenging goals in modern Physics. Particle Physics provides well motivated candidates for dark matter, among which a generic weakly-interacting massive particle (WIMP) stands out for its simplicity and the fact that WIMP candidates can be found in many theories proposing new physics at the TeV scale, such as Supersymmetry, models with Universal Extra Dimensions and Little Higgs Theories. I will review the properties of some of the main WIMP candidates and their detectability (with special emphasis on direct detection experiments). I will also address the strategies that can be used to discriminate among them in the case of a future detection.

Background Events

Weakly Interacting Massive Particle (WIMP) direct detection experiments are just reaching the sensitivity required to detect Galactic dark matter in the form of neutralinos (or indeed any stable weakly interacting particle). Detection strategies and data analyses are often based on the simplifying assumption of a standard spherical, isothermal halo model, but observations and numerical simulations indicate that galaxy halos are in fact triaxial and anisotropic, and contain substructure. the annual modulation and direction dependence of the event rate (due to the motion of the Earth) provide the best prospects of distinguishing WIMP scattering from background events, however these signals depend sensitively on the local WIMP velocity distribution. I briefly review the status of WIMP direct detection experiments before discussing the dependence of the annual modulation signal on astrophysical input, in particular the structure of the Milky Way halo, and the possibility that the local WIMP distribution is not smooth.

Abstract The Scotogenic Model is one of the most minimal models to account for both neutrino masses and dark matter (DM). In this model, neutrino masses are generated at the one-loop level, and in principle, both the lightest fermion singlet and the lightest neutral component of the scalar doublet can be viable DM candidates. However, the correct DM relic abundance can only be obtained in somewhat small regions of the parameter space, as there are strong constraints stemming from lepton flavour violation, neutrino masses, electroweak precision tests and direct detection. For the case of scalar DM, a sufficiently large lepton-number-violating coupling is required, whereas for fermionic DM, coannihilations are typically necessary. In this work, we study how the new scalar singlet modifies the phenomenology of the Scotogenic Model, particularly in the case of scalar DM. We find that the new singlet modifies both the phenomenology of neutrino masses and scalar DM, and opens up a large portion of the parameter space of the original model.
