Have we found conclusive evidence for dark matter through direct detection experiments?

Abstract

We employ a SUSY-model-independent method to examine the remaining evidence for the low mass dark matter. Using the XENON100's recent result of 224.6 live days ×\times 34kg exposure and PICASSO's result published in 2009, we have obtained a constrain of couplings, an<0.6\| {{a_n}} \| < 0.6 and ap<1.0\| {{a_p}} \| < 1.0, corresponding to the spin-dependent cross section of σn<5.6×1038{\sigma_n} < 5.6 \times {10^{- 38}}cm2^{2} and σp<1.6×1037{\sigma_p} < 1.6 \times {10^{- 37}}cm2^{2}. Spin-independent isospin violating dark matter model also failed to reconcile the recent result from XENON100 with the positive results from DAMA and CoGeNT.
