Abstract:
L'existence de la matière noire est connue en raison de ses effets gravitationnels et, bien que sa nature reste inconnue, un des candidats principaux est une particule massive interagissant faiblement (WIMP) ayant une masse de l'ordre de 100 GeV/c2 et un couplage avec la matière ordinaire à ou en dessous de l'échelle faible. Dans ce contexte, DarkSide-50 cherche à observer des collisions WIMP-nucléon dans une chambre de projection temporelle à double phase d'argon liquide située dans le sous-sol du Laboratoire National du Gran Sasso (LNGS), en Italie.

The existence of a significant non-baryonic component to the Universe is widely accepted, with worldwide efforts underway trying to detect this so-called dark matter.

The neutralino, arising in supersymmetric extensions to the standard model of particle physics, provides a particularly well-motivated candidate.

Several astrophysical observations, both on a galactic and cosmological scales, showing that there’s a “missing mass” in the observable Universe, can be explained assuming a non-luminous kind of matter, hence called “dark matter”.

Dark matter particles in the form of supersymmetric Weakly Interacting Massive Particles (WIMPs) could accumulate in the centre of the Sun because of gravitational trapping.

Data from the IceCube 22-string neutrino telescope have been searched for signals from dark matter annihilations in the Sun. Highly sophisticated analysis methods have been developed to discern signal neutrinos from the severe background of atmospheric particle showers. No signal has been found in a dataset

There is now compelling evidence that ordinary baryonic matter only represents 15% of the matter content of the Universe. Observational results suggest that the remaining 85% may be constituted of dark matter possibly in the form of weakly interacting massive particles (WIMPs). One of the potential ways to detect these WIMPS is to look for their scattering interactions with nuclei. This is the basis of direct detection experiments. In particular, galactic signature direct detection experiments look for the characteristic properties of the WIMP signal. The current landscape of galactic signatur

CRESST has an established analysis procedure to evaluate the energy of the events it detects, in an attempt to detect WIMP dark matter. It was shown that unless eight classes of contaminant event were removed prior to this analysis, the output energy spectrum would be significantly biased. For both scientific and practical reasons, the removal process should be blind, and a series of cuts were developed to flag these events automatically, without removing any true events. An event simulation package was developed to optimise these cuts. It was shown that noise fluctuations could also reduce CR

Abstract:
This licentiate thesis presents contributions to the luminosity measurement from the data recorded by the ATLAS detector in 2017 using a track-counting technique, as well as a search for dark matter in the ATLAS experiment using 139 fb-1 of √s = 13 TeV pp collision data delivered by the LHC from 2015 to 2018. Track-counting luminosity measurements in low-luminosity operations are performed to study the effect of low collision rates on luminosity determination. The luminosity measured in a calibration transfer procedure using the track-counting technique is used to correct the pile-up dependenc

Abstract:
Dark matter (DM) constitutes one of the most intriguing but so far unresolved issues in physics. In many extensions of the Standard Model of particle physics, the existence of a stable Weakly Interacting Massive Particle (WIMP) is predicted. The WIMP is an excellent DM particle candidate. One of the most interesting scenarios is the creation of monochromatic gamma-rays from the annihilation or decay of these particles. This type of signal would represent a “smoking gun” for DM, since no other known astrophysical process should be able to produce it. In this thesis, the search for spectral line
