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, $\Vert a_n\Vert <0.6$ and $\Vert a_p\Vert <1.0$, corresponding to the spin-dependent cross section of ${\sigma }_n<5.6\times 10^{-38}$cm${}^2$ and ${\sigma }_p<1.6\times 10^{-37}$cm${}^2$. Spin-independent isospin violating dark matter model also failed to reconcile the recent result from XENON100 with the positive results from DAMA and CoGeNT.
