TLDR
Constraints on light dark matter (DM) models using ionization signals in the XENON1T experiment are reported, and no DM or CEvNS detection may be claimed because the authors cannot model all of their backgrounds.
Abstract
We report constraints on light dark matter (DM) models using ionization signals in the XENON1T experiment. We mitigate backgrounds with strong event selections, rather than requiring a scintillation signal, leaving an effective exposure of (22±3) tonne day. Above ∼0.4  keVee, we observe 30  MeV/c2, and absorption of dark photons and axionlike particles for mχ within 0.186–1  keV/c2.

The Dark Photon

TL;DR: The dark photon is a new gauge boson whose existence has been conjectured as mentioned in this paper, and it is dark because it arises from a symmetry of a hypothetical dark sector comprising particles completely neutral under the Standard Model interactions.

Projected WIMP sensitivity of the XENONnT dark matter experiment

Elena Aprile, +141 more
TL;DR: In this paper, the authors predict the experimental background and project the sensitivity of XENONnT to the detection of weakly interacting massive particles (WIMPs) in a 4 t fiducial mass.

Projected WIMP Sensitivity of the XENONnT Dark Matter Experiment

Elena Aprile, +138 more
TL;DR: In this article, the authors predict the experimental background and project the sensitivity of XENONnT to the detection of weakly interacting massive particles (WIMPs) using the profile construction method, in order to ensure proper coverage.

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.
