Higgs? ? ? ! DT-EM 2 12/13/11
Higgs Detection: H -> gg Rare decay channel: BR~10 -3 ü Look for mass peak Ø Demand for excellent ECAL performance CMS detector The combined energies of the signal photons would cluster at the mass of the Higgs boson. In contrast, background events include photon pairs with a variety of energies. events Higgs signal background DT-EM 2 12/13/11 Mass

Neutrinos faster than light ? ? OPERA (Oscillation Project with Emulsion-t. Racking Apparatus) DT-EM 2 12/13/11
Present status "One of the eventual systematic errors is now out of the way, but the search is not over. They are more checks of systematics currently under discussion, one of them could be a synchronisation of the time reference at CERN and Gran Sasso independently from the GPS, using possibly a fiber" said Jacques Martino, Director of National Institute of Nuclear and Particle Physics of French CNRS ~25 ppm !
