Physicists at the University of Texas at Arlington celebrated the announcement this morning that an international research project in which they participate has discovered a new particle.
Scientists at CERN, the European Organization for Nuclear Research, in Geneva stopped short of claiming that the particle is the elusive Higgs boson, a theoretical particle that could explain where mass comes from, Bloomberg News reported.
“As a layman, I think I would say ‘we have it,’” CERN director Rolf-Dieter Heuer said at a news conference. It will take at least three to four years of research to fully understand the properties of the observed particle, Heuer said.
The announcement brings humankind closer to answering a millennia-old question that the ancient Greeks wrestled with: What is matter made of? The particle is a key to the Standard Model, a theory explaining how the universe is built, and its existence would help scientists gain a better understanding of how galaxies hold together. It also could open a door to exploring other parts of physics such as superparticles or dark matter that telescopes can’t detect.
The Center of Excellence for High Energy Physics at UT Arlington is part of the U.S. team contributing to the experiments, both in Switzerland and on campus, where it operates a massive computing center for the ATLAS project.
Kaushik De, director of the center, said the discovery is one of the biggest in 30 years in physics.
“Without the Higgs there would be no matter,” he said. “No stars, no planets. Only light would exist, and maybe some other unknown massless objects. Everything would move fast — at the speed of light. Nothing in the universe could move slower or faster. It would indeed be an unusual universe.”
The field that generates mass for objects is named for UK physicist Peter Higgs, who in the 1960s was one of the first scientists to outline a working theory on how elemental particles achieve mass.
Higgs was one of four of the theorists attending today’s meeting in Geneva. He wiped a tear from his eye as the findings were presented, Bloomberg News reported.
"For me, it’s really an incredible thing that it’s happened in my lifetime,” he said.
