Witherell Addresses Budget
To All Hands Today
Director Michael Witherell will discuss "The Budget and Prospects for the Future" at three All-Hands meetings today in Ramsey Auditorium. The three sessions will be organized alphabetically by the last names of employees: A-G at 10 AM, H-O at 1 PM, and P-Z at 3 PM. There is no streaming video.
The 10 AM meeting will be available on labwide TV on channel nine (9).

Fermilab Arts Series Presents Festival of Four

Festival of Four is a unique blend of two classical guitars, flamenco guitar and flute; it is an exotic cross between the Los Angeles Guitar Quartet, Quartetto Gelato and The Gipsy Kings. The sonic colors created by Chilean-born flutist Viviana Guzman with her collection of over 100 flutes from diverse cultures, the skills of international award-winning guitarist Marc Teicholz, the breathtaking rhythms of flamenco guitar virtuoso Guillermo Rios and the composition and arranging talents of guitarist Richard Patterson combine to shatter the boundaries of traditional chamber music and create a sound all their own.
The flamenco artist Guillermo Rios returned to the U.S. after 7 years touring with some of Spain's most respected flamenco dancers such as Jose Greco. Hailed by the New York Times as "an imaginative artist," flutist Viviana Guzman has been known to belly-dance on occasion during Festival of Four concerts. Both Guzman and Rios have played at such venues as Carnegie Hall, as well. Richard Patterson enjoys an active international career performing as a feature soloist in North and South America, Europe, Asia and Africa. Marc Teicholz, classical guitarist, has won numerous awards and is featured on the pilot soundtrack for George Lucas' Young Indiana Jones.
Festival of Four will perform this Saturday, February 17 at 8:00 p.m in Ramsey Auditorium. Tickets cost $18/$9 for ages 18 and under. For further information, visit our Web page or call (630) 840-ARTS (2787) weekdays between 9 a.m. and 4 p.m for telephone reservations. Will-Call tickets may be picked up, or available tickets purchased, at the lobby box office on the night of the event beginning at 7:00 p.m.

From Stanford Report, February 15, 2005
"Quantum Diaries" reveal the secret lives of modern physicists
by Kathy Bellevin
What is it like to be a physicist in 2005, 100 years after Einstein pushed physics to a new frontier? A new website featuring researchers at Stanford and around the globe is helping answer that question by cataloging the daily lives of more than 25 physicists.
Quantum Diaries celebrates the World Year of Physics by recording the experiences, thoughts, impressions, triumphs and disappointments of these men and women in their blogs, which is short for weblogs, or web-based logs.
The response so far has been stunning. Quantum Diaries was launched on Jan. 13 and garnered more than 45,000 visits by the end of the month. Some of the physicists' weblogs are getting nearly 1,000 visits per day.

Fun With Two Photons At CDF
|

The CDF diphoton transverse momentum (qT) distribution
compared to several theoretical predictions. (Click on image for larger version.) |
|
In collider experiments, interaction events having two
photons among the final decay products ("diphoton final
states") are a signature of many interesting physics
processes. For example, at the LHC, one of the main
discovery channels for the Higgs search is through the Higgs
decaying into two photons. An excess of diphoton production
at high invariant mass (high energies) could also be a
signature of large extra dimensions, and in many theories
involving physics beyond the Standard Model, certain decays
of heavy new particles generate a diphoton signature.
However, the QCD production rate for diphotons is large
compared to most new physics, so an understanding of the QCD
production mechanism is a prerequisite to searching reliably
for new physics in these diphoton events. In addition, the
two-photon final state is interesting in its own right,
allowing for precision tests of many aspects of perturbative
QCD.
In the first QCD publication from Run II, a group of CDF
researchers has measured the rate of diphoton production as
a function of several kinematic variables. In the figure
above, the diphoton transverse momentum (qT) distribution is
compared to the predictions from several theoretical
programs: "resummed" ResBos, DIPHOX NLO
(next-to-leading-order), and the parton shower Monte Carlo
Pythia. Comparisons to other kinematic variables can be
found in the paper
(hep-ex/0412050). Good agreement is observed with the
resummed and NLO predictions in different regions of phase
space. For agreement, everywhere, however, a resummed full
NLO calculation will be necessary, a challenge for the
theoretical physicists.
