Evening 2 - Dark Matter Searches
- Kyle Leach (Colorado School of Mines)
There is strong evidence for the existence of Dark Matter. One possible form of Dark Matter is strongly self-interacting Dark Matter, or Strongly Interacting Massive Particles (SIMP), modelled after Quantum Chromodynamics (QCD). It should also be noted that, to date, no direct detection of any kind of dark matter has been made. Direct detection of dark matter at accelerators is a high priority...
The Scintillating Bubble Chamber (SBC) collaboration is developing novel particle detectors sensitive to low-energy (sub-keV) nuclear recoils by combining existing bubble chamber technology with liquid noble detectors. This approach leverages the insensitivity to electronic recoils characteristic of bubble chambers alongside the scintillation yield from a liquid noble active medium. SBC aims...
The PICO collaboration uses superheated bubble chambers in search of dark matter through direct detection. The PICO-500 experiment is the next generation PICO detector, expected to reach world-leading sensitivity for weakly interacting massive particle (WIMPs) interactions. Building upon the success of previous PICO detectors, this next-generation apparatus will consist of $\sim$250 liters of...
The latest results from the DEAP-3600 experiment will be presented. DEAP-3600 experiment is a direct dark matter search that employs single-phase liquid argon to detect potential dark matter interactions in the universe. Located 2 km underground at SNOLAB in Sudbury, Canada, the experiment uses a spherical acrylic vessel capable of holding 3600 kg of liquid argon. This vessel is monitored by...
The PICO experiment uses bubbles chambers, where the fluid is superheated, to directly look out for the existence of WIMPs dark matter particles. Fluorocarbon material (CF3I or C3F8) is used as an active fluid that allow to study inelastic dark matter-nucleus scattering interaction. This technology is designed in such a way that it has the ability to reject electron-recoil interaction and be...
The detection of dark matter remains a central challenge in particle physics. Liquid argon (LAr) based experiments, like DEAP-3600, must understand potential background signals mimicking dark matter in order to achieve maximum sensitivity. Argon-1, a modular LAr detector at Carleton University utilizing silicon photomultipliers, provides a platform to study key background sources, aiding not...
