Dark Matter Searches with LUX

Understand

We report here on the results from the Weakly Interacting Massive Particle (WIMP) search with the LUX dark matter experiment.

• LUX, a two-phase xenon time projection chamber (TPC) with 250 kg of active mass, has been operated from 2012 until 2016.
• During the operation, we observed no evidence for WIMP elastic scattering events.
• LUX achieved the most stringent limit on both the WIMP-nucleon spin-independent cross section (1.1$\times{10}^{-46}$ cm$^2$ for a 50 GeV/c${}^{2}$, 90% C.L.) and on the WIMP-neutron spin-dependent cross section (1.6$\times{10}^{-41}$ cm$^2$ for a 35 GeV/c${}^{2}$, 90% C.L.).
