U.S. scientists played a significant role in advancing the theory and in discovering the particle that proves the existence of the Higgs field, the Higgs boson. Colin Jessop, professor of physics at the University of Notre Dame, is the leader of the Notre Dame team that works on the Compact Muon Solenoid (CMS) collaboration at CERN. The team’s experiment is one of two Large Hadron Collider (LHC) experiments that shared the Higgs boson discovery. Last year, when the scientists unveiled new data, Jessop said, “All of a sudden I saw a peak that indicated the Higgs, and I fell off my chair, literally. I was walking around in a daze for a day because it was so stunning.” Notre Dame high-energy physicists Alexey Drozdetskiy, Michael Hildreth, Kevin Lannon, Nancy Marinelli, Randy Ruchti and Mitchell Wayne are also part of the Notre Dame CMS team. “The Notre Dame group has significant leadership roles in a number of key areas on the CMS experiment,” Wayne said, “including building part of the detector, helping operate the detector while data was collected, developing software, analyzing data and working on upgrades to improve the detector’s performance.” In the 1960s, Higgs and Englertalong with other theorists published papers introducing key concepts in the theory of the Higgs field. In 2012, scientists on the international ATLAS and CMS experiments, performed at the Large Hadron Collider at CERN laboratory in Europe, confirmed this theory when they announced the discovery of the Higgs boson. The prediction and then discovery of the Higgs boson, almost 50 years apart, highlights the close connection between the work of experimental physicists, who labor to test and overturn the laws of physics in laboratories around the world, and theoretical physicists, who work to build mathematical frameworks for understanding nature from all that data. “Sometimes, like in the case of the Higgs boson, theory is years ahead of experiment. In other cases, theorists are shocked by experimental results and spend years trying to incorporate them into our models,” said Antonio Delgado, who, along with Ikaros Bigi, Christopher Kolda and Adam Martin, works on the theory of the Higgs boson at Notre Dame. The Notre Dame experimental group is part of a larger collaboration of nearly 2,000 physicists from U.S. institutions that participate in the CMS and ATLAS experiments, making up about 23 percent of the ATLAS collaboration and 33 percent of CMS at the time of the Higgs discovery. By remotely accessing and analyzing data through high-capacity networks and grids, the U.S. scientists contribute their knowledge and expertise. According to Fermilab, “U.S. scientists provided a significant portion of the intellectual leadership on Higgs analysis teams for both experiments.” The discovery of the Higgs boson at CERN was the culmination of decades of effort by experimental and theoretical physicists and engineers around the world, at the LHC as well as the Tevatron accelerator at Fermilab, and the Large Electron Positron accelerator, which once inhabited the tunnel where the LHC resides.
