The ATLAS experiment narrows the range in the search for the Higgs boson

The ATLAS experiment presented its latest results on the search for the Higgs boson at the Lepton Photon 2011 symposium in Mumbai, India (22-27 Aug.,). This constrains the hypothetical Higgs boson to have a mass either in a narrow range between 115 and 146 GeV or a set of higher, unfavored, values. The Queen Mary ATLAS group participates in the analysis of ATLAS data and contributed in key areas of the ATLAS semiconductor tracker, and in the design and commissioning of the ATLAS calorimeter trigger which selects events for further scrutiny amongst the roughly 800 million collisions per second produced by the Large Hadron Collider.
