On December 13th, 2011 the ATLAS and CMS experiments presented the status of their searches for the Standard Model Higgs boson in a seminar at CERN. Both experiments have seen hints of Higgs boson production in the mass range of 120-130 GeV, but not significant enough to prove the Higgs particle existence. Instead, they have limited its possible existence within the mass ranges of 116-130 GeV (ATLAS) and 115-127 GeV (CMS).
The QMUL Particle Physics Research Center participates in the ATLAS experiment, and has given substantial contributions to the design of the Semiconductor Tracker for the precision tracking of charged particles, and the design of the Level-1 Calorimeter Trigger, the electronics that selects events of interest from the one billion collisions per second that occur at the center of the ATLAS detector.
