XENON100 and the LHC are two of the most promising machines to test the physics beyond the Standard Model .
In the meantime , indirect hints push us to believe that the dark matter and Higgs boson could be the two next fundamental particles to be discovered .
Whereas ATLAS and CMS have just released their new limits on the Higgs searches , XENON100 obtained very recently strong constraints on DM-proton elastic scattering .
In this work , we show that when we combined WMAP and the most recent results of XENON100 , the invisible width of the Higgs to scalar dark matter is negligible ( \lesssim 10 \% ) , except in a small region with very light dark matter ( \lesssim 10 GeV ) not yet excluded by XENON100 or around 60 GeV where the ratio can reach 50 % to 60 % .
The new results released by the Higgs searches of ATLAS and CMS set very strong limits on the elastic scattering cross section , even restricting it to the region 8 \times 10 ^ { -46 } \mathrm { cm ^ { 2 } } \lesssim \sigma _ { S - p } ^ { SI } \lesssim 2 \times 10 ^ { - % 45 } \mathrm { cm ^ { 2 } } in the hypothesis 135 \mathrm { ~ { } GeV } \lesssim M _ { H } \lesssim 155 \mathrm { ~ { } GeV } .
