Neubauer notes, “The Higgs boson discovery ten years ago will go down in history as one of humanity’s great scientific achievements. ![]() Meanwhile, Professors Anne Sickles and Matthias Grosse Perdekamp are on the team at the ATLAS experiment building detectors for and studying the heavy-ion collision runs at the LHC, which produce quark-gluon plasma-the stuff of the early universe. Shelton is an expert on the phenomenology of exotic ways that the discovered Higgs boson might decay and be observed. And two new faculty members are using LHC data to search for new physics beyond the standard model electroweak theory, where the Higgs boson resides: Professor Ben Hooberman, with ATLAS data and Professor Jessie Shelton, who is a leader on the theory side of current LHC studies. Today at UIUC, Mark Neubauer continues to lead the experimental efforts on Higgs physics. The discovery and the scientific tools and methods that enabled this discovery opened the door to further exciting investigations-even through to today and into the future. Since 1994, members of the Illinois team were heavily involved in the experiment’s design, construction, commissioning, data taking, and data analysis. UIUC physicists Mark Neubauer, Tony Liss, Steven Errede and Deborah Errede and their team contributed to this discovery through the ATLAS experiment. In just ten years physicists have made tremendous steps forward in our understanding of the universe, not only confirming early on that the particle discovered in 2012 is indeed the Higgs boson but also allowing researchers to start building a picture of how the pervasive presence of a Higgs field throughout the universe was established a tenth of a billionth of a second after the Big Bang. “I remember with emotion the day of the announcement, a day of immense joy for the worldwide particle physics community and for all the people who worked tirelessly over decades to make this discovery possible.” It marked both the end of a decades-long journey of exploration and the beginning of a new era of studies of this very special particle,” says Fabiola Gianotti, CERN’s Director-General and the project leader and spokesperson of the ATLAS experiment at the time of the discovery. “The discovery of the Higgs boson was a monumental milestone in particle physics. One year later it won François Englert and Peter Higgs the Nobel Prize in Physics for their prediction made decades earlier, together with the late Robert Brout, of a new fundamental field, known as the Higgs field, that pervades the universe, manifests itself as the Higgs boson and gives mass to the elementary particles. The discovery was a landmark in the history of science and captured the world’s attention. Ten years ago, on July 4 2012, the ATLAS and CMS collaborations at the Large Hadron Collider (LHC) announced the discovery of a new particle with features consistent with those of the Higgs boson predicted by the standard model of particle physics. ![]() The event was recorded by ATLAS on 1, 11:07:47 CEST. The masses of the lepton pairs are 87.9 GeV and 19.6 GeV). The landmark discovery of the Higgs boson at the Large Hadron Collider exactly ten years ago, and the progress made since then to determine its properties, have allowed physicists to make tremendous steps forward in our understanding of the universe Event display of a Higgs decay (H -> 2e2mu candidate event with m(4l) = 122.6 (123.9) GeV without (with) Z mass constraint.
