We perform a generalized analysis of data from WIMP search experiments for point-like WIMPs of arbitrary spin and general Lorenz-invariant WIMP-nucleus interaction. We show that in the non-relativistic limit only spin-independent (SI) and spin-dependent (SD) WIMP-nucleon interactions survive, which can be parameterized by only five independent parameters. We explore this five-dimensional parameter space to determine whether the annual modulation observed in the DAMA experiment can be consistent with all other experiments. The pure SI interaction is ruled out except for very small region of parameter space with the WIMP mass close to 50 GeV and the ratio of the WIMP-neutron to WIMP-proton SI couplings $-0.77\le f_n/f_p\le -0.75$. For the predominantly SD interaction, we find an upper limit to the WIMP mass of about 18 GeV, which can only be weakened if the constraint stemming from null searches for energetic neutrinos from WIMP annihilation the Sun is evaded. None of the regions of the parameter space that can reconcile all WIMP search results can be easily accommodated in the minimal supersymmetric extension of the standard model.

The statement that this DAMA result is completely excluded by the results of these cryogenic experiments and is inconsistent with the SUSY interpretation (see, for example, [ref] ) is simply wrong (see also discussions in [ref] ).

The dominant contribution to the direct detection signal comes from Higgs exchange with scattering cross section per nucleon approximately given by [ref] σ∼m_r^2/2π(_X sin2þ/v_hm_h^2 )^2 f_p^2, where $m_r$ is the reduced mass of the DM-proton given by $m_r=m_Xm_p/(m_X+m_p)$ and we have assumed that the interactions with protons and neutrons are the same with f_p = m_p[∑_u,d,s f_T_q+6/27f_T_G] ∼0.30 m_p, where, following [ref] , we have used $(f_T_u,f_T_d,f_T_s,f_T_G)=(0.018, 0.027, 0.037, 0.917)$.
