Experimentalists and Theorists Converge at the Tevatron Connection|
|Theorist Tao Han of the University
of Wisconsin, Madison, presented at the Tevatron Connection earlier this week.

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
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."
On Monday night, participants and their families attended
the Tevatron Connection party at the Kuhn Barn. (Click on image for larger version.)|

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).

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
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.
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.

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 firstname.lastname@example.org
to sign up for the tour.
