DT-EM2 13/12/ /13/11DT-EM2
Meeting with PH (retreat) DT is foreseen to stabilize at just above 70 staff. 12/13/11DT-EM2
New DT building! 12/13/11DT-EM2
New member (?) Mechanical Technician /Technicien(ne) en mécanique Technician in the field of Mechanics in the Physics Department (PH), Detector Technology Group (DT) Technicien(ne) en mécanique dans le Département de physique (PH), groupe Technologie des détecteurs (DT) Programme: Staff Staff Category: Technicians Number of posts: 1 Posted Date: 11/11/2011 Closing Date: 05/01/2012 Reference: PH-DT LD 12/13/11DT-EM2
Higgs Detection: H -> Rare decay channel: BR~10 -3 Look for mass peak Demand for excellent ECAL performance 12/13/11DT-EM2 events Mass background Higgs signal 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. CMS detector
The Higgs search as of 18/11/ /13/11DT-EM2 To be continued……..
12/13/11DT-EM2 Neutrinos faster than light ?? OPERA (Oscillation Project with Emulsion-tRacking Apparatus)
12/13/11DT-EM2 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 BUT, neutrino oscillations indicates a non-zero masss!!! ~25ppm !
