Two theorists predicting the existence of the Higgs boson get the Physics Nobel Prize  
Peter Higgs and Francois Englert won the Nobel Prize in Physics for predicting the existence of the Higgs boson. The particle has been discovered on July 4, 2012, by teams of physicists from the ATLAS and CMS experiment, using the Large Hadron Collider at CERN in Geneva, Switzerland. This discovery and subsequent measurements were the culmination of a decades-long quest to understand how mass arises. Our Experimental High Energy Physics Group has been involved in the research and discovery of the Higgs boson for 30 years.

The group members, Profs. Roderich Engelmann, John Hobbs, Robert McCarthy, Michael Rijssenbeek, Robert Dean Schamberger and Dmitri Tsybychev, along with their graduate students and post-doctoral researchers, carry out research with the ATLAS experiment team. The group made a number of contributions to the Higgs discovery and ongoing follow up studies. The group was responsible for design and construction of instrumetation needed for the measurements of the Higgs boson decays to electrons and photons. These measurements formed the main evidence in the 2012 discovery analyses. The group also led the effort to calibrate the measured masses in these decays.

Our group leads ongoing studies of the Higgs boson, in particular analyzing additional Higgs boson reactions which must occur if the standard theory is correct. We are beginning participation in analysis searching for other reactions which may occur if the standard theory is incomplete.

The section of the ATLAS apparatus which measures electron and photon energies, is a modernized version of the apparatus used in the D0 experiment at Fermilab. D0 was led for 13 years by Distinguished Research Prof. Paul D. Grannis including the period during which another fundamental particle, the top quark was discovered. Analysis of D0 data, along with that of its sister experiment CDF, established initial evidence for the Higgs boson prior to the ATLAS and CMS discovery announcements.
