For their pioneering and outstanding leadership rôles in the making of the ATLAS and CMS experiments

In July 2012, the ATLAS and CMS collaborations announced the discovery of a new heavy particle at a mass around 125 GeV. Its properties were strikingly similar to those of a Higgs boson, a long-sought particle expected from the mechanism for electroweak symmetry breaking that was introduced almost 50 years ago by Robert Brout, François Englert and Peter Higgs. Experimental confirmation of the Higgs boson presented monumental challenges because of its relatively large mass and small production rates in cleanly detectable modes. The observation has required the creation of experiments of unprecedented capability and complexity, designed to discern the signatures that correspond to the Higgs boson. Their creation has required the use, and in many cases the development, of cutting-edge technologies. In addition, the gigantesque structures were supplemented with appropriate software and computing systems that enabled the analysis of the vast amounts of data that had to be collected. This work has required the collective efforts of over three thousand physicists and engineers from each experiment. These teams collected the data and analyzed it to establish that a Higgs boson, very much like the one in the Standard Model, exists.  

The prize recognizes the collective efforts of the ATLAS and CMS collaborations, as well asthose of three physicists, P. Jenni for the ATLAS experiment and M. Della Negra and T. Virdeefor the CMS experiment, who provided pioneering ideas and led the teams that designed,constructed and commissioned the detectors over the course of nearly twenty years.

The 2013 High Energy and Particle Physics Prize, for an outstanding contribution to High Energy Physics, is awarded to the ATLAS and CMS collaborations, “for the discovery of a Higgs boson, as predicted by the Brout-Englert-Higgs mechanism”, and to Michel Della Negra, Peter Jenni, and Tejinder Virdee, “for their pioneering and outstanding leadership rôles in the making of the ATLAS and CMS experiments”.
