UT Dallas Physicists Play Role in Higgs Quest
University of Texas at Dallas researchers played a role in groundbreaking experiments that led to the discovery of a new elementary particle of matter, one that is “consistent” with the long-sought-after Higgs boson. When the much-buzzed-about July 4 announcement of the new particle was made by officials at the CERN research facility in Geneva, UT Dallas faculty members, postdoctoral scientists and students involved in the research were positioned around the globe – in China, Australia and Europe. The research results were so highly anticipated by the scientific community that investigators on-site at CERN, including UT Dallas physics undergraduate student Cyrille Chiari, lined up the night before just to get a seat in the packed auditorium for the early-morning statement. “To give an idea of how motivated people here are, the fire alarm went off and no one moved an inch,” Chiari said in an email. “It went on for 10 minutes and still no one left.”
Musical Forces Collide
What began as entertainment at a dinner to celebrate the construction of a Large Hadron Collider (LHC) experiment at the CERN laboratory in Switzerland culminated in an unusual side project among scientists, including UT Dallas’ Dr. Joe Izen. Izen, professor of physics and principal investigator for the UT Dallas High Energy Physics Group, works on the ATLAS experiment studying the head-on collisions of high-energy particles. Upon joining ATLAS in 2007, Izen quickly discovered fellow scientists there shared his interest in playing music. After coming to Dallas to work on the Superconducting Super Collider (SSC) in 1991, Izen formed a band called Squirrelheads in Gravy to play old-time Southern mountain music for contra dances hosted by the North Texas Traditional Dance Society.
Award Funds Students Particle Physics Research
UT Dallas physics student Alex Palmer has won an award from theDepartment of Energy (DOE) Office of Science Graduate Fellowship Programto pursue research on particle physics. The terms of the fellowship are generous. The $50,500 award includes support for tuition and fees, an annual living stipend and an annual research stipend. It is renewable for up to three years, as long as the fellow makes progress toward a PhD and attends a yearly research conference. “I’m very excited because it grants me a lot of extra freedom in graduate school,” said Palmer, who will graduate this May with a bachelor’s in physics. “I can likely get into research during my first semester, rather than just taking classes and being a TA. Additionally, if for some reason I decide to switch specialties within physics, I won’t be a year behind.”
Space Model Brings Vast Distances Down to Scale
A physics colloquium on Wednesday began with a dedication of a poster that places the closest star to our sun squarely atop UT Dallas. The event was the result of an effort by the Gruppo Astrofili di Piacenza astronomy club in Italy to illustrate the vastness of space. The club created an “Astronomy Park” scale model of the solar system using posters to mark the locations of various heavenly bodies. Club members set the scale at 1:5,000,000,000, or about 79,000 miles per inch, so that the model could fit inside a public park in Piacenza, Italy.
Center is a New Space to Explore the Sciences
The Science Learning Center’s tile exterior was inspired by two patterns: atomic emission spectra of gases, and human DNA when it is separated in a process called gel electrophoresis. The Science Learning Center doubles the number of instructional science labs at UT Dallas and brings labs from a variety of disciplines together in one facility. Classes in chemistry, biology, physics, the geosciences, and science and mathematics education will be taught in the new space. Designed with the participation of faculty, including Physics Professor Joseph M. Izen, who chaired the building’s advisory committee, every aspect of the facility has been designed to satisfy specific academic goals.
