| Oscillatory behavior of the B-sub-s meson discovered | ||
| ||
|
The CDF collaboration announced that they have met the exacting standard to claim discovery of unimaginably rapid transitions between matter and antimatter: 3 trillion oscillations per second.
Dr. Raymond L. Orbach, Undersecretary for Science in the U.S. Department of Energy, congratulated the CDF collaboration on the result. "This remarkable tour de force details with exquisite precision how the antiworld is tied to our everyday realm," Dr. Orbach said. "It is a beautiful example of how, using increasingly sophisticated analysis, one can extract discovery from data from which much less was expected. It is a triumph for Fermilab." The CDF discovery of the oscillation rate, marking the final chapter in a 20-year search, is immediately significant for two major reasons: reinforcing the validity of the Standard Model, which governs physicists' understanding of the fundamental particles and forces; and narrowing down the possible forms of supersymmetry, a theory proposing that each known particle has its own more massive "super" partner particle. Many experiments worldwide have worked to perform high precision measurements of the behavior of matter and antimatter, especially as it pertains to strange, charm and bottom quarks. Scientists hope that by assembling a large number of precise measurements involving the exotic behavior of these particles, they can begin to understand why they exist, how they interact with one another and what role they played in the development of the early universe. Most importantly, they could also be the place in which to look for new physics beyond the Standard Model, which scientists believe is incomplete. Although none of these particles exists in nature today, they were, however, present in great abundance in the early universe. Thus, scientists can only produce and study them at large particle accelerators.

University of Chicago Chronicle, September 21, 2006: Physicists on faculty support ILC construction Two beams of subatomic particles, each measuring far less than the diameter of a human hair, travel at the speed of light from opposite ends of an 18-plus-miles- long track. In precise alignment, they smash head-on into each other to simulate the conditions that existed shortly after the big bang.
Particle physicists around the globe nurture this vision for the proposed International Linear Collider, which could lead to revolutionary discoveries about the characteristics of matter and energy. Still at issue: where to build it and to what extent the United States will become involved.

| Dumpster violations | ||
Sometimes problematic wastes come from onsite and sometimes they come from offsite. If it is determined that an employee, user or contractor is responsible for dumping offsite wastes into a lab dumpster, they may be charged for the cost of the clean up and subject to disciplinary action. Below are some reminders for the proper management of waste materials.
