Direct detection of dark matter - Wikipedia
Direct detection of dark matter is the science of attempting to directly measure dark matter collisions in Earth-based experiments. Modern astrophysical measurements, such as from the cosmic microwave background, strongly indicate that 85% of the matter content of the universe is unaccounted for. [1]
Dark matter (DM) makes up most of the matter component in the Universe, as suggested by astrophysical and cosmological observations Zhao-Huan Yu (Melbourne) Dark Matter Direct Detection July 2017 2 / 37
New approaches to dark matter detection - Nature Reviews Physics
2022年9月14日 · Decades of searching for theoretically motivated dark matter candidates have yielded no results, so the research community is starting to adopt different strategies for detecting dark...
Quantum Enhancement in Dark Matter Detection with Quantum …
2024年7月8日 · We propose a novel method to significantly enhance the signal rate in qubit-based dark matter detection experiments with the help of quantum interference. Various quantum sensors possess ideal properties for detecting wavelike dark matter, and qubits, commonly employed in quantum computers, are excellent candidates for dark matter detectors.
Direct detection searches for dark matter particles using …
2024年12月13日 · In this article, the Canadian participation in experiments looking for interactions between nuclei and dark matter particles with mass at the 10 GeV scale and higher will be explored; specifically, superheated bubble chambers by the PICO collaboration, and liquid argon (LAr) detectors by the DEAP collaboration.
Scattering meets absorption in dark matter detection
4 天之前 · Direct detection experiments have started to explore dark matter scattering off electrons and nucleons through light mediators. Mediators with sub-keV masses are efficiently produced in the Sun and can be absorbed in the same detectors that probe dark matter scattering. We investigate the interplay of dark matter scattering and mediator absorption for two models with a dark photon as mediator ...
Scattering meets absorption in dark matter detection
4 天之前 · Atomic Dark Matter has a richer direct detection phenomenology than Dirac Dark Matter, due to the presence of both dark atoms and dark constituents in the galactic halo. We first review the phenomenology of Atomic Dark Matter in cosmology and astrophysics and determine the viable parameter space. We then discuss the prospects for direct ...
New bounds on dark matter coupling from a global network of …
We report on the first Earth-scale quantum sensor network based on optical atomic clocks aimed at dark matter (DM) detection. Exploiting differences in the susceptibilities to the fine-structure constant of essential parts of an optical atomic clock, i.e., the cold atoms and the optical reference cavity, we can perform sensitive searches for DM ...
Prospects for the detection of Dark Matter with Long-lived …
1 天前 · Abstract. The operation of the next generation of gamma-ray observatories will lead to a great advance in dark matter searches. In this paper, we use the hidden sectors hypothesis within the so-called secluded models to calculate the capabilities of the Southern Wide-field Gamma-ray Observatory (SWGO) to detect gamma-ray signatures produced by dark matter particles concentrated in the Sun.
Direct Detection of Dark Matter: A Critical Review - MDPI
2024年2月8日 · Dark matter, despite being weakly interacting at the microscopic level, can influence astrophysical systems on a larger scale, such as stellar evolution. Thet indirect detection of dark matter involves searching for the products of dark matter particle annihilation or decay, such as photons, fermion pairs, and neutrinos.
