| Physicist wins Panofsky Prize for research at Fermilab | |
| |
|
Former Fermilab researcher Bruce Winstein received the American Physical Society's 2007 Panofsky Prize along with Italo Mannelli of University of Pisa (INFN), and Heinrich Wahl, of the University of Ferrara (CERN). The award was given to the three physicists for discovering "direct CP violation" in particle decays--subtle differences between matter and their antimatter counterparts. Observing these slight differences is important because it may help explain why antimatter does not naturally exist in the universe, while matter is abundant. This question has puzzled physicists since antimatter was first detected in 1933.
The prize is given for outstanding efforts made over a substantial part of a physicist's career. Winstein, a University of Chicago professor, received the 2007 award for his work during the 80s and 90s at the Fermilab Tevatron, which culminated with the KTeV experiment. KTeV recorded and precisely compared millions of kaon and antikaon decays. In 1999, KTeV found that kaons and antikaons decayed to the two pion final states at slightly different rates--definitively showing that matter and antimatter behave differently when they decay. "The fact that we could find out something important about nature was very satisfying," said Winstein, who is currently working on a cosmology experiment dealing with cosmic microwave background radiation. "It was certainly an important event in my life and the life of many of the experimenters." Mannelli and Wahl worked on the NA48/2 experiment at CERN, which investigated the same topic.
Winstein was a KTeV spokesperson from 1992 to 1998. He made crucial contributions to the design and construction of KTeV, and to data analysis after KTeV started running. "Bruce was the intellectual father of the kaon physics program at the Tevatron," said Bob Tschirhart, who worked on the experiment with Winstein and now leads continuing KTeV data analysis efforts with Ed Blucher of the University of Chicago. "It's hard to say enough good things about Bruce's grasp of physics. It was really special to have a leader with such a great understanding of both the underlying theory and experimental techniques."

The Register, October 24, 2006: Scientists catch exotic new particles Researchers working at the Fermilab particle accelerator in the US have discovered two new kinds of particle, exotic relatives of the common-or-garden proton and neutron.
Dr Todd Huffman of the University of Oxford, one of the UK scientists in Collider Detector at Fermilab (CDF), said although the particles have been predicted by theory, they haven't been seen before.

| Encouraging excellence | ||
| Today's column is written by Roger Dixon, head of the Accelerator Division.
This past week I had the opportunity to serve as a judge for the Siemens-Westinghouse Science and Technology Competition for the 8th
Upon my return to the laboratory, I had to shift gears quickly because we were having a difficult time with the accelerator complex. The Tevatron was down for repairs after a pesky mouse caused a power glitch that resulted in a quench that damaged two magnets. It is always a gratifying experience to watch the dedicated and talented people in the AD bring the complex beast back to life. When I arrived, AD people had been working around the clock for several days, and the repairs were nearing completion. I could not help but compare the incredible efforts I see routinely at our laboratory to the superb efforts of the Siemens competitors. These quality efforts occur in all of our divisions and sections and in the work of our users. The people who make these efforts are a vital resource. If our laboratory and our country are to meet the challenges of the future, it is crucial that laboratory management, our funding agencies, and everyone in leadership positions all the way up the chain to the President encourage this excellence by making a commitment to the dedicated people who routinely make these extraordinary efforts. Excellence must be nurtured. It does not result from filling out forms. |
