Novel direct detection constraints on light dark matter
TL;DR: In this paper, the authors derive novel constraints from the inevitable existence of a subdominant, but highly energetic, component of particle dark matter generated through collisions with cosmic rays, which limits the DM-nucleon scattering cross-section to be below the threshold for both spinindependent and spindependent scattering of light DM.

Abstract: All attempts to directly detect particle dark matter (DM) scattering on nuclei suffer from the partial or total loss of sensitivity for DM masses in the GeV range or below. We derive novel constraints from the inevitable existence of a subdominant, but highly energetic, component of DM generated through collisions with cosmic rays. Subsequent scattering inside conventional DM detectors, as well as neutrino detectors sensitive to nuclear recoils, limits the DM-nucleon scattering cross section to be below ${10}^{\ensuremath{-}31}\text{ }\text{ }{\mathrm{cm}}^{2}$ for both spin-independent and spin-dependent scattering of light DM.

Dark matter induced Brownian motion
TL;DR: In this article, a novel approach for directional, light dark matter searches inspired by the high precision position measurements achieved in gravitational wave detectors is discussed, where movable masses are subject to an effect similar to Brownian motion induced by the scattering with dark matter particles which exhibits certain characteristics and could be observed.
Sun Heated MeV-scale Dark Matter and the XENON1T Electron Recoil Excess
Yifan Chen,Ming-Yang Cui,Jing Shu,Xiao Xue,Guan-Wen Yuan,Guan-Wen Yuan,Qiang Yuan,Qiang Yuan,Qiang Yuan +8 more
TL;DR: In this paper, the authors explore the possibility to explain the XENON1T anomaly by the MeV-scale dark matter (DM) heated by the interior of the Sun due to the same DM-electron interaction as in the detector.
Azimuthal asymmetry in cosmic-ray boosted dark matter flux
09 Mar 2023
TL;DR: In this paper , the most stringent constraints on the DM-electron scattering cross section from the Super-Kamiokande (SK) IV data were derived, which improved the previous constraints from the SK-IV full-sky data by more than an order of magnitude.
Scattering Searches for Dark Matter in Subhalos: Neutron Stars, Cosmic Rays, and Old Rocks
09 Jun 2022
TL;DR: In this paper , the authors investigate alternative and promising means to identify sub-halo dark matter interacting with standard model particles, and identify new detection strategies involving single-star measurements and Galactic disk surveys, and obtain the first bounds on self-interacting dark matter in subhalos from the coldest known pulsar.

Particle dark matter: Evidence, candidates and constraints
TL;DR: The current status of particle dark matter, including experimental evidence and theoretical motivations, including direct and indirect detection techniques, is discussed in this paper. But the authors focus on neutralinos in models of supersymmetry and Kaluza-Klein dark matter in universal extra dimensions.

The Structure of Cold Dark Matter Halos
TL;DR: In this article, the authors use N-body simulations to investigate the structure of dark halos in the standard Cold Dark Matter cosmogony, and they find that the density of a halo correlates strongly with the halo mass.
