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.
Angels Lecture to Separate Physics from Fiction
Its plot centers on a secret society’s mission to destroy the Vatican using a small amount of antimatter. Author Dan Brown’s Angels & Demons novel is a work of fiction set in the all-too-real setting of the Large Hadron Collider (LHC) at the European particle physics laboratory CERN, before the action moves to the Vatican City and Rome. The best-selling novel was adapted for celluloid by director Ron Howard and makes its big screen debut May 15. Tom Hanks portrays world-renowned Harvard symbologist Robert Langdon, and parts of the film were actually filmed at the LHC. Though a compelling page-turner and brilliant blend of science and fiction, elementary particle physicists readily spot when the novel departs from real science and the realm of the possible to the unreal possibility of an antimatter catastrophe, courtesy of the minuscule amounts generated at CERN. “Antimatter is real, unlike Kryptonite,” said Dr. Joseph M. Izen, a professor of physics. “There actually was a dedicated experiment at CERN to trap antiprotons and to make antihydrogen a few years ago, but that was not part of the LHC program. There is a conversion of mass to energy when matter and antimatter annihilate, but the quantity of antimatter in Angels & Demons, the trap holding it and its appearance as a floating, pulsating antiblob in the book/movie are fictional plot devices. These days, more antiprotons are being made by the accelerator complex at Fermilab in the U.S. than are being produced at CERN.”
U. T. Dallas High Energy Physics Researchers Behind Discovery of Mysterious New Particle
RICHARDSON, Texas (July 7, 2005) – Scientists from The University of Texas at Dallas (UTD) High Energy Physics (HEP) Group were instrumental in a discovery disclosed to the scientific community last week of a mysterious new subatomic particle – dubbed Y(4260). The researchers are part of the BaBar experiment, a United States Department of Energy (DOE) particle physics collaborative research program being conducted at the Stanford Linear Accelerator Center (SLAC). The discovery could ultimately provide scientists with a deeper understanding of the makeup of the universe. Details of the breakthrough are contained in a paper that was submitted to the journal Physical Review Letters. In addition, the discovery was reported last week at a research conference in Uppsalla, Sweden, and an announcement was made, also last week, by SLAC (http://www.slac.stanford.edu/gen/pubinfo/pr/20050701/). Major contributors to the discovery include four researchers from UTD – HEP Group scientist Dr. Shuwei Ye, Professor and Physics Department head Dr. Xinchou Lou, Physics Professor Dr. Joseph Izen and Ph.D. student Glenn Williams. The group’s research is funded by the DOE.
