TLDR
The spin-dependent WIMP-neutron limit is the most sensitive constraint to date.
Abstract
We present experimental constraints on the spin-dependent WIMP (weakly interacting massive particle)-nucleon elastic cross sections from LUX data acquired in 2013. LUX is a dual-phase xenon time projection chamber operating at the Sanford Underground Research Facility (Lead, South Dakota), which is designed to observe the recoil signature of galactic WIMPs scattering from xenon nuclei. A profile likelihood ratio analysis of 1.4×10^{4}  kg day of fiducial exposure allows 90% C.L. upper limits to be set on the WIMP-neutron (WIMP-proton) cross section of σ_{n}=9.4×10^{-41}  cm^{2} (σ_{p}=2.9×10^{-39}  cm^{2}) at 33  GeV/c^{2}. The spin-dependent WIMP-neutron limit is the most sensitive constraint to date.

The waning of the WIMP? A review of models, searches, and constraints

TL;DR: A review of the WIMP paradigm with focus on a few models which can be probed at best by these facilities, and Collider and Indirect Detection will not be neglected when they represent a complementary probe.

Improved limits on scattering of weakly interacting massive particles from reanalysis of 2013 LUX data

D. S. Akerib, +100 more
TL;DR: This new analysis incorporates several advances: single-photon calibration at the scintillation wavelength, improved event-reconstruction algorithms, a revised background model including events originating on the detector walls in an enlarged fiducial volume, and new calibrations from decays of an injected tritium β source and from kinematically constrained nuclear recoils down to 1.1 keV.

WIMP dark matter candidates and searches—current status and future prospects

TL;DR: The present experimental status of dark matter theory and experiment is overview, which includes current bounds and recent claims and hints of a possible signal in a wide range of experiments: direct detection in underground laboratories, gamma-ray, cosmic ray, x-rays, neutrino telescopes, and the LHC.

Supersymmetric Dark Matter

TL;DR: In this article, the neutralino is considered as a superpartner in many supersymmetric theories, and the cosmological abundance of neutralino and the event rates for both direct and indirect detection schemes are discussed.

First results from the LUX dark matter experiment at the Sanford Underground Research Facility

D. S. Akerib, +101 more
TL;DR: The first WIMP search data set is reported, taken during the period from April to August 2013, presenting the analysis of 85.3 live days of data, finding that the LUX data are in disagreement with low-mass W IMP signal interpretations of the results from several recent direct detection experiments.

Modern theory of nuclear forces

TL;DR: In this article, the nuclear forces can be derived using effective chiral Lagrangians consistent with the symmetries of QCD, and the status of the calculations for two and three nucleon forces and their applications in few-nucleon systems are reviewed.

Dark Matter Candidates from Particle Physics and Methods of Detection

TL;DR: The identity of dark matter is a question of central importance in both astrophysics and particle physics as discussed by the authors, and recent progress has greatly expanded the list of well-motivated candidates and the possible signatures of the dark matter.
