| Russian Summer Student Will Soon Leave Fermilab |
||
|
||
|
Sergei Tsaregorodtsev is one of eight Russian students who have come to work at Fermilab for the summer. Tsaregorodtsev will be leaving on September 28, but he has mixed feelings about it. Between creating a more user-friendly interface for the GUI computer program and playing basketball in the village after work, Tsaregorodtsev has managed to make himself at home here. "My parents wrote letters asking if I missed them," he said. "But I was having too much fun to say yes."
Tsaregorodtsev's visit is the result of an outreach effort that was created by Victor Yarba, who is the head of the Technical Division. Yarba says the undergraduate students' time at Fermilab gives them a chance to "see how they like the technology and a chance to see who is who." He started this program in 2001, with the goal of attracting high-quality students to American PhD programs in accelerator physics. And if Tsaregorodtsev is a good model, then Yarba's hope might pan out; Tsaregorodtsev, who had never left Russia before this summer, has already met with American professors and plans to apply for a PhD program in accelerator physics at the Illinois Institure of Technology. "This has been a wonderful opportunity for me," said Tsaregorodtsev. "There is nothing this big in Russia. I never could have done something like this if I hadn't come here."

Grid3 Ends Productive Two-Year Run
"New discoveries in astrophysics, simulations in particle physics, earthquake engineering optimizations and analyses of protein sequences in biology all benefited from extended use of Grid3 resources," said Fermilab's Ruth Pordes, one of the Grid3 coordinators. "These results would not have been possible without interfacing individual projects' computing resources to Grid3's common infrastructure."
Grid3 was initially created to demonstrate specific technologies at the Supercomputing 2003 conference. It proved so successful that operation was continued well after the conference, to the benefit of participating scientists. Grid3 represented breakthrough collaboration between the National Science Foundation-funded GriPhyN and iVDGL projects, the Department of Energy's Office of Science-funded PPDG project, the U.S. ATLAS and U.S. CMS particle physics experiments and the Condor and Globus teams—collaboration that will continue with the Open Science Grid infrastructure.

From The Economist, September 1, 2005 Strange behaviour: Particles that exist only fleetingly help make everyday matter magnetic In the world of particle physics, there is no such thing as nothing. Particles of matter, and their anti-matter counterparts, are forever flitting in and out of existence. Theorists have predicted that the presence of such transient visitors has little effect on everyday life. However, a group of experimental physicists has just shown this view to be mistaken.

| Do Top Quarks Resonate? |
||
|
||
|
A large part of the Run II physics program is dedicated to the study of the top quark and its interactions with other particles.
Many theories that predict physics beyond the Standard Model (SM) postulate heavy particles that could be produced at the Tevatron and decay into top quark pairs. One way to search for these particles is to reconstruct the mass of the pair and, if such a particle existed, a peak or "resonance" in the mass spectrum could be observed. A team from the University of Florida working at the CDF experiment has recently completed a search for such a particle using Run II data. Their analysis uses a novel technique to reconstruct probabilistically the invariant mass of the system with improved accuracy. This analysis approach allows them to exclude the existence of new heavy particles predicted by a theory called "topcolor" with masses below 700 GeV. This is currently the world's best limit, surpassing the CDF Run I result by 220 GeV! The data shows an intriguing peak at about 500 GeV. The analysis favors an extra 30% contribution to the top pair production cross section originating from resonance production. Statistical tests show that this is not a large enough effect to get too excited just yet. CDF and the Florida team looks forward to include more data in the analysis and to test further the hypothesis of a new 500 GeV particle that makes top quark pairs resonate. |

World Year of Physics Picnic It's the World Year of Physics and we are making a special effort to visit school children and tell them about the fun of physics. Visiting is fun too! If you would like to help, please join us at a picnic this Friday, 12:00 - 1:00 at the Users Center. You only need to bring your enthusiasm, we will provide the rest. Please tell Nancy Lanning at lanning@fnal.gov by Thursday at 4:00 pm if you can come.
