During the past few decades, many astronomical and cosmological studies provided strong evidence for the existence of dark matter.
Though, to this day, we do not have any hint about what dark matter is, which motivates taking any opportunity to probe this question.
One possible solution is to extend the Standard Model with a new U(1) gauge group.
This introduces a new mediator: a light...

PICO-40L is a bubble chamber detector with a target material of superheated C₃F₈, located at the SNOLAB underground research facility outside Sudbury, Ontario. With its abundance of non-zero-spin fluorine nucleons in the detector target and its effective blindness to electron recoil interactions, it is projected to set world-leading exclusion limits in the spin-dependent...

The DEAP-3600 experiment at SNOLAB primarily searches for Weakly Interacting Massive Particle (WIMP) dark matter candidates through interactions with argon nuclei. The detector consists of 3.3 tonnes of liquid argon housed in a spherical acrylic vessel which is viewed by 255 photomultiplier tubes. Data have been taken stably from November 2016 to March 2020 and the detector is currently...

3564. Dark Matter Dilution Mechanisms and Large Scale Structure

Oral (Non-Student) / Orale (non-étudiant(e))

Entropy production is a necessary ingredient for addressing the over-population of thermal relics. It is widely employed in particle physics models for explaining the origin of dark matter. A longlived particle that decays to the known particles, while dominating the universe, plays the role of the dilutor. We point out the impact of its partial decay to dark matter on the primordial matter...

3620. (G*) Status and Prospects of the SNO+ Experiment

Symposia Day (PPD - PPD) - Discovering New Paths to Discovery: New Technologies and Methods to Uncover BSM Physics | Découvrir de nouvelles voies vers la découverte : Nouvelles technologies et méthodes pour découvrir la physique au-delà du modèle standard

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

The SNO+ Experiment is a versatile multipurpose neutrino detector situated at SNOLAB, with the primary goal of searching for neutrinoless double beta decay. After a successful operating phase as a water Cherenkov detector, the SNO+ target medium was switched to a liquid scintillator to increase the light yield of the detector, thereby enabling a much richer physics programme. In addition to...
