Experimentalists and Theorists Converge at the Tevatron Connection
Tevatron Connection
Theorist Tao Han of the University of Wisconsin, Madison, presented at the Tevatron Connection earlier this week. (Click on image for larger version.)
Monday and Tuesday, about 200 physicists from Fermilab and collaborating institutions gathered in Ramsey Auditorium for the Tevatron Connection, a series of presentations and discussions on Run II physics at the Tevatron. Members of the CDF, DZero and MiniBooNE experiments presented new results; theorists followed with presentations on the same topics and facilitated discussion between presenters and the audience.

"We've never before had this kind of interaction between theorists and DZero and CDF," said Young-Kee Kim, CDF co-spokesperson and one of the conference organizers. "I've gotten a lot of good feedback from people, and I hope we have more occasions like this."

CDF and DZero presented many new and updated results, including searches for supersymmetry, extra dimensions, Higgs bosons, leptoquarks and single-top production; measurements of the mass of the top quark; lifetimes, masses and decays of B mesons; and results from QCD physics. MiniBooNE, which has seen 380,000 neutrino events so far, presented results from muon neutrino data. On Monday evening, participants and their families gathered in and around Kuhn Barn for a mid-conference dinner and party.

"I thought it went very well," said DZero co-spokesperson John Womersley, a member of the organizing committee. "The talks were good, but the discussions were even better."

Science in the movies: Hollywood or bust
Last month, a handful of scientists who have toyed with the idea of writing for the movies were given a masterclass by Tinseltown's finest. Jonathan Knight joined them.
In the 1997 disaster movie Volcano, whole sections of Los Angeles are demolished by lava. For advice on the film, the production crew turned to Christopher Vogler, one of Hollywood's top story consultants. "Lava actually makes a tinkling sound like glass as it cools," Vogler says, "but they wanted it to roar like a freight train. Any volcanologist who saw the movie probably thought it was a comedy."

Record Federal Support for Academic S&E Activities
An NSF survey shows that federal support to universities, colleges, and nonprofit institutions for science and engineering activities reached a new peak in fiscal year 2002, with the Department of Health and Human Services providing over 50 percent of that support. According to NSF, "Federal agencies obligated a new high of $24.4 billion for academic science and engineering (S&E) activities in FY 2002." This is an increase of $1.9 billion, or more than 8 percent, over the FY 2001 level of $22.5 billion. The previous year's growth was even higher, climbing13 percent from FY 2000 to FY 2001. This information is reported in a four-page June 2004 NSF InfoBrief entitled "Federal Science and Engineering Obligations to Academic and Nonprofit Institutions Reached Record Highs in FY 2002" (NSF04-324).

CDF Probes Electroweak Forces
Photon transverse momentum spectrum, E T(gamma), for W+gamma (left) and Z+gamma (right) candidates selected in the leptonic decay channel. The data are compared with the Standard Model and background expectation. (Click on images for larger version.)
Interactions between elementary particles are described by the exchange of bosons. Within electroweak theory, these force propagators are the W and Z bosons, and the photon. High energy proton antiproton collisions at the Tevatron produce these particles singly in large quantities, but they are rarely produced in pairs. Measuring the production rate of two of these electroweak bosons in a single event probes the interactions between these particles, and allows experimental tests of the Standard Model's electroweak theory.

A group of CDF researchers has analyzed more than 200 pb-1 of collisions looking for events containing both a Z and a gamma, or a W and a gamma. The analysis is based upon selecting the electron and muon (lepton) decay channels of the Z or W, and then identifying an isolated photon in those events having ET > 7 GeV, and delta R separation from the lepton > 0.7. The measured cross section, or production rate, for W+gamma is 19.7 +\- 2.8 pb, and for Z+gamma is 5.3 +\- 0.7 pb, both in good agreement with theoretical predictions. The W-gamma and Z-gamma production properties, such as the transverse energy spectrum of the produced photon, are also well modeled by the electroweak prediction. These measurements, in combination with those of WW, WZ and ZZ pairs, will be used to place limits on physics beyond the Standard Model, including searches for compositeness of the W and Z bosons.

The CDF W/Z + gamma working group is (left to right) Beate Heinemann (Liverpool), Michael Kirby (Duke), Helen Hayward (Liverpool), Al Goshaw (Duke), and Naho Tanimoto (Okayama). (Click on image for larger version.)

Wilson Hall Power Outages
Listed below are the proposed dates and times for the upcoming 'shutdown' related power outages that will affect Wilson Hall:
August 28 and 29 for 8 hours starting at approximately 7:00 a.m.
September 13 for half an hour starting at approximately 7:00 a.m.
September 18 for 8 to 10 hours starting at approximately 7:00 a.m.
September 24th for half an hour starting at approximately 7:00 a.m.
For more information, contact the Wilson Hall Building Manager, Stan Boyson.

Cruisin' the Lab August 17
The next Cruisin' the Lab will be Tuesday, August 17 at 11:30 a.m. and 12:15 p.m. Docents from the Education Office will give tours of the Interpretative Trail. The group will meet at the Lederman Center. There will be no van rides from Wilson Hall to the Lederman Center. If you would like to go on the tour, please be sure to wear long pants and comfortable walking shoes. Mosquito repellant with DEET would also be helpful. Call x3092 or email edreg@fnal.gov to sign up for the tour.

New Book Purchase Suggestion Lists
New Book purchase suggestion lists for the week of August 10 are now available online. These include Majors book lists in four subject areas. There is also an Amazon suggestion list in the form of a shopping cart, viewable by entering the password "library."

Recreation Office Closed Today
Due to unforseen circumstances, the Recreation Office will be closed today. All other Recreation sites will be open as usual, such as the Village Pool, Day Camp and the Recreation Facility.

CDF Posters Available in Public Affairs
Free posters from the CDF experiment are available in limited quantities to anyone who would like one. If you are interested, stop by the Office of Public Affairs.

Wilson Hall Interior Window Washing This Week
The cleaning crew started washing the interior windows in Wilson Hall this week. Please remove any papers that are taped to the windows in your office. Please move any papers or other items on your desk that are near the windows. For questions, contact Enixe Castro at x2798. The windows will be cleaned according to this schedule:
August 12: 6th, 5th, 4th floors
August 13: 3rd, 2nd, 1st floors
