News Articles

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.”
Physicists Join Massive Collider in Search for Truths
The device that may answer how the universe came to be is the largest and one of the most expensive devices ever created. The Large Hadron Collider (LHC) sits beneath the surface of the earth along the Franco-Swiss border outside Geneva. The arms of the world’s largest particle accelerator form a 17-mile tunnel beneath the earth. Within this tunnel, protons are accelerated to almost the speed of light before being slammed against an opposing stream of protons in a head-on crash of cosmic proportions. The goal? To answer such fundamental physics questions as, What is the origin of mass? What is dark matter? And, what happens to matter when it’s heated to 100,000 times the temperature at the center of the sun?
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.
UTD Physics Department to Host Monthly Meetings of Texas Astronomical Society
RICHARDSON, Texas (Dec. 12, 2005) – The Texas Astronomical Society (TAS) of Dallas, one of the premier amateur astronomy organizations in the country, will begin holding its monthly meetings on the campus of The University of Texas at Dallas (UTD) starting in January. The new cooperative arrangement between the two organizations should prove beneficial to students and members of the public, according to a UTD professor involved in bringing the group to the school. “We believe this partnership will provide tangible benefits to UTD students with an interest, professional or otherwise, in astronomy, as well as to Dallas-area high school students and members of the general public who become involved in joint astronomy-related outreach programs envisioned by the university and TAS,” said Dr. Joe Izen, a professor in UTD’s physics department, which will host the monthly meetings. “We look forward to working with TAS, and are excited to be able to welcome many of the society’s nearly 600 members to campus each month.”
ATLAS Cavern Banjo Video Wins Third Place
Joe Izen, principal investigator for UT Dallas' high energy physics group, entered Banjo Hangout'sBanjos in Unusual Places challenge and won third place out of 28 entries. In Izen's video, he playsRed Hills Polka and Chinese Breakdown on his banjo in the ATLAS cavern. Izen picked up the banjo in the 80s when he was a PhD student working on the CLEO experiment. He played during night shifts at CLEO and later in other experiments he worked on, most recently in the ATLAS Control Room at CERN during theLarge Hadron Collider's first run. "Around 4AM when the body clock starts to go to sleep, if everyone was okay with it, I'd play my banjo," says Izen. Izen's band Squirrelheads in Gravy has two tracks included in Resonance, a double-CD featuring music of physicists working on the ATLAS experiment, the proceeds of which help to fund theHappy Children's Home in Pokhara, Nepal. Banjo Hangout runs a challenge every month, and Banjos in Unsual Places was its April edition.
