Abstract
The latest XENON100 data severely constrains dark matter elastic scattering off nuclei, leading to impressive upper limits on the spin-independent cross-section. The main goal of this paper is to stress that the same data set has also an excellent spin-dependent sensitivity, which is of utmost importance in probing dark matter models. We show in particular that the constraints set by XENON100 on the spin-dependent neutron cross-section are by far the best at present, whereas the corresponding spin-dependent proton limits lag behind other direct detection results. The effect of nuclear uncertainties on the structure functions of xenon isotopes is analysed in detail and found to lessen the robustness of the constraints, especially for spin-dependent proton couplings. Notwithstanding, the spin-dependent neutron prospects for XENON1T and DARWIN are very encouraging. We apply our constraints to well-motivated dark matter models and demonstrate that in both mass-degenerate scenarios and the minimal supersymmetric standard model the spin-dependent neutron limits can actually override the spin-independent limits. This opens the possibility of probing additional unexplored regions of the dark matter parameter space with the next generation of ton-scale direct detection experiments.

The limit on the spin independent cross section settled by LUX experiment [ref] being so stringent (almost 4 to 5 orders of magnitudes compared to the spin dependent one, also set by LUX) that the conservative upper limit on $⟨σv ⟩$ is uniquely determined by the upper limit on $σ^SD_χN$, and more precisely $σ^SD_χn$ given by LUX[LUX, like other xenon-type detectors, is much more sensitive to the scattering cross section on neutrons since the contribution from neutrons to the nuclear spin exceeds by an order of magnitude the one of protons.] which is the strongest spin dependent constraint[An analysis on the spin dependent constraint from $χn$ interaction was already made in 2012 for the XENON experiment in [ref] .] at present [ref] .

For the choice of parameter $Λ$ that can account for the monochromatic photon cross section within the Fermi LAT sensitivity, the corresponding spin-dependent cross section is found to be less than $10^-20$pb, far below the recent direct detection [ref] and neutrino telescope [ref] bounds.
