Description
Dark matter detection has been an exciting frontier over the past twenty years. Particle physicists and astrophysicists are probing wide mass ranges to hunt for different dark matter (DM) candidates. In this parallel session, the speakers are welcome to present the experimental and theoretical works on both direct and indirect DM detection as well as the collider detection of DM, including such as WIMP candidates and beyond.
Cold Dark matter is one of the major constituents of the leading cosmological model for our Universe, with many ongoing experimental efforts at directly detecting interactions of the hypothetical particle with terrestrial detectors.
SuperCDMS SNOLAB is a Generation-2 dark matter experiment under construction at SNOLAB in Sudbury, Canada. The experiment will employ two types of state of the...
The CRESST-III (Cryogenic Rare Event Search with Superconducting Thermometers) experiment, located in the Gran Sasso underground laboratory (LNGS, Italy), aims at the direct detection of light dark matter (DM) particles.
Scintillating CaWO$_4$ crystals operated as cryogenic detectors at mK temperatures are used as target material for elastic DM-nucleus scattering. The simultaneous...
The CDEX program pursues the direct detection of light dark matter candidates with an array of germanium detectors since 2009 at the deepest operating underground site located in Sichuan, China. Searches of modulation effect of light WIMPs[1], WIMPs-nucleus interaction via Midgal effect[2], dark photon model[3], solar axions and axion-like particles[4] as well as the...
Measuring dark matter (DM) signals via electron recoil provides an important means
for the direct detection of light DM particles. In this talk, I will show that the recent XENON1T anomaly with electron recoil energy around (2 − 3) keV can be naturally explained by the exothermic inelastic scattering between DM and electrons in a 2-component DM scenario. The stability of the heavier component...
The dark matter direct detection rates are highly correlated with the phase space distribution of
dark matter particles in our galactic neighbourhood. In this paper we make a systematic study of the
impact of astrophysical uncertainties on electron recoil events at the direct detection experiments
with Xenon and semiconductor detectors. We find that within the standard halo model there...
The possibility to detect gravitational waves (GW) from planetary-mass primordial black hole (PBH) binaries with electromagnetic (EM) detectors of high-frequency GWs is investigated. We consider two patented experimental designs, based on the inverse Gertsenshtein effect, in which incoming GWs passing through a static magnetic field induce EM excitations inside either a TM cavity or a TEM...
Many new physics models like SUSY can have dark matter candidates. Collider experiment provides a unique approach search for dark matter candidates. Like neutrinos, dark matter candidates, once produced from high energy particle collisions, would escape from detection and leave a signature of missing energy. The production mechanism through effective field theory model, simplified model and...
After the Higgs discovery, the precise determination of the Higgs boson properties became one of the top priorities for experimental particle physics. The Circular Electron Positron Collider is therefore proposed. Colliding the electron and positron at a tunnel with the main ring circumference of 100 km, the CEPC is expected to deliver 1 Million Higgs bosons in an extremely clean collision...
The DArk Matter Particle Explorer (DAMPE) is a satellite-borne, calorimetric type, high-energy-resolution space cosmic ray and gamma-ray detector. It was launched in December 2015 and has been stably operating for more than five years. Its three major scientific objectives are dark matter indirect detection, cosmic ray physics and gamma-ray astronomy. Precise measurements of the all-electron,...
Recently, a considerable amount of attention has been given to the search for ultralight dark matter by measuring the oscillating length changes in the arm cavities of gravitational wave detectors. Although gravitational wave detectors are extremely sensitive for measuring the differential arm length changes, the sensitivity to dark matter is largely attenuated, as the effect of dark matter is...
The extended excess towards the Galactic Center (GC) in gamma rays inferred from Fermi-LAT observations has been interpreted as being due to dark matter (DM) annihilation. In a recent paper my collaborators and I performed a new likelihood analyses of the GC and showed that when including templates for the stellar galactic and nuclear bulges, the GC shows no significant detection of a DM...
Axion dark matter can be produced by the decay of cosmic strings, leading to large amplitude, small scale density perturbations in the axion field. These perturbations for the seeds for axion ``miniclusters’’: small and dense dark matter clumps, with mass $M\approx 10^{-12} M_{\odot}$. The seeds go on to form minicluster halos via hierarchical structure formation. By comparison between the...
From years ago, there have been established many different experiments for the detection of Axion Like Particles (ALPs) as a promising candidate of dark matter. The coupling of ALPs with the standard model particles has been explained with some interaction Lagrangians. Many experiments try to detect ALPs by their interaction with photons in the context of a static magnetic field using the well...
