Parallel session talk

Understanding the nature of Dark Matter (DM) is one of the open issues in modern physics. In this context, XENON project aims to lead the effort on DM direct detection using ton-scale xenon dual-phase time projection chamber technology, operating in a low background environment.

258. Status of Dark Matter Searches with Liquid Argon Detectors

Shawn Westerdale (University of California, Riverside)

8/30/22, 2:35 PM

Dark Matter

Parallel session talk

Despite its abundance, little is known about the particle nature of dark matter. Liquid argon-based detectors deployed in underground laboratories are powerful probes for direct detection dark matter searches, due to their scalability to large target masses, the low price of argon, their strong particle identification power using pulse shape discrimination to separate electronic and nuclear...

128. Exotic dark matter searches with the Majorana Demonstrator

8/30/22, 3:30 PM

Dark Matter

Parallel session talk

With its excellent energy resolution and ultra-low backgrounds, the high-purity germanium detectors in the Majorana Demonstrator enable several searches for beyond the Standard Model physics. These range from the primary neutrinoless double beta decay search to searches for several classes of exotic dark matter models, axions, and tests of quantum mechanical conservation laws. In this talk,...

251. The Outer Detector of the LUX ZEPLIN dark matter direct detection experiment

Harvey Birch (University of Michigan)

8/30/22, 4:00 PM

Dark Matter

Parallel session talk

The LUX-ZEPLIN (LZ) detector consists of 7 tonnes (5.6 tonnes fiducial) of liquefied xenon in a
dual-phase Time Projection Chamber (TPC), which is sensitive to the nuclear and electron recoils
induced by Weakly Interacting Massive Particles (WIMPs). Among the various type of background
particles, neutrons pose a great threat to the WIMPs searches due to the indistinguishable...

Dark Matter

Parallel session talk

Potassium-40 (${}^{40}$K) is a naturally-occurring, radioactive isotope impacting understanding of nuclear structure, geological ages spanning timescales as old as the Earth, and rare-event searches including those for dark matter and neutrinoless double beta decay. In many advancing fields, the accelerating precision required for new discoveries has been limited by knowledge of the ${}^{40}$K...

The SPICE and HeRALD experiments aim to probe dark matter (DM) masses down to 10 MeV, with upgrade paths to sub-MeV masses. The project is currently in a preparatory R&D phase focused on first pushing Transition Edge Sensor (TES) recoil energy thresholds into the sub-eV regime, and then applying this next generation of sensors to a variety of well-motivated target materials. The HeRALD...

8. No show: Characterization of the cosmogenic background in NaI(Tl)

Ms YIYI ZHONG (Department of Nuclear Physics and Accelerator Applications, ARC Centre of Excellence for Dark Matter Particle Physics, The Australian National University)

Dark Matter

Parallel session talk

Cosmogenic background is increasingly recognized as being important for dark matter direct detection experiments, especially as other sources of background have been well-understood and massively reduced, so as to increase the sensitivity for detecting rare dark matter events. This key background in NaI(Tl) arises from the cosmogenic radioisotopes like ${}^3$H and ${}^{22}$Na, that are low in the...

3. No Show: Laboratory limits on the annihilation or decay of dark matter particles

Tim Michael Heinz Wolf (MPIK)

Dark Matter

Parallel session talk

Several pieces of evidence point toward the existence of Dark Matter (DM). One detection strategy is the search for self-annihilation or decay into standard model particles. We present a novel technique to constrain the DM annihilation rate and the DM decay rate by employing Earth-based detectors such as XENON1T or Borexino. While the primary goal of these detectors is either direct detection...

4. No show: The Modified Archimedes Principle

Mr Arnold Lasky (unaffiliated)

Dark Matter

Parallel session talk

Abstract

The Modified Archimedes Principle (MAP) is a modified gravity theory, which holds that a massive body, such as the sun, or a mass equivalent vacuum energy body, such as a halo, which is immersed in the vacuum energy of space, displaces a volume of such space that is centered on such body, through a mass repelling displacement force that complements the mass attracting gravitational...

Matthew Citron (Univ. of California Santa Barbara (US))

Dark Matter

Parallel session talk

In dark sector theories, DM is just one particle within a hidden sector of the Universe that could be every bit as complex as our own. This can lead to a wide range of exotic signatures that could be observed at the LHC, including long-lived particles, DM scattering and millicharged particles. As these signatures are often invisible to general purpose detectors, in this talk I will focus on...

Dark Matter

Parallel session talk

The $A$ Prime ($A\prime$) Experiment was a search performed at Hall A of the Thomas
Jefferson National Accelerator Facility (Jefferson Lab, or JLab), looking for evidence
of a dark vector gauge boson (also called a‘dark photon’). The dark
photon of interest, denoted as $A\prime$, is theorised to interact with the Standard
Model through kinematic mixing, which is characterised by a strength...
