Pier Oddone Welcomed in
With Round of Applause|
Yesterday morning at 8:30 a.m., Pier Oddone entered Wilson Hall for his
first "on-site" day as new director of Fermilab. He didn't know that a large crowd
of employees and well-wishers waited for him just inside the doors. His wife
Barbara guided him in at the right time. As he stepped into the building,
the crowd burst into applause to welcome him to his new position.
With a broad smile, Oddone thanked the crowd and made his way
into the atrium, shaking everyone's hand as he went, babies included.

Fermilab Will Celebrate the|
Witherell Years Today
Cake and Ice Cream with Mike!
All Fermilab employees, users, and contractors are invited to enjoy cake
and ice cream with Mike Witherell today between 11:45 a.m. to 12:45
p.m. in the Wilson Hall Atrium.
Come thank Mike for his years of service to the Laboratory and wish him
the best in the future.
Former Director |
A public science symposium to honor Mike Witherell,
called "Fermilab Science: The Witherell Years," will be held in Ramsey
Auditorium today at 1:00 p.m. This symposium will celebrate Mike Witherell's
contributions to Fermilab and the science advancements that have taken
place here over the past six years. A reception in the Atrium will follow the
symposium from 5:00 p.m. to 6:30 p.m.
GDE Director's Corner,|
This week, the "8th ACFA Workshop on Physics and Detectors at the Linear
Collider" is being held in Daegu, Korea. ACFA stands for the Asian Committee
for Future Accelerators. It was formed in 1996 as a result of an initiative
by Professor Z. Zheng, Director of IHEP, and Professor H. Sugawara, Director
General of KEK. The present chair of ACFA is Professor Shin-ichi Kurokawa of
ACFA has actively pursued its stated goal "to strengthen regional collaboration
in accelerator-based science." In particular, a strong focus of ACFA is the
effort toward a linear collider and Asia's role in this effort. The committee
has published three formal statements regarding the linear collider, most
recently on November 4, 2004, following the decision to base the design of the
linear collider on "cold" technology. Although much of the work in Asia had
been on "warm" technology, in that statement, ACFA lends support to the
technology decision, as well as to the concept of developing a world-wide
effort toward realizing the ILC.

A New Survey - SDSS-II will Map the Universe, the Milky Way and Dark Energy
Dr. Richard Kron, director of the Sloan Digital Sky Survey, announced a new undertaking that will complete the largest survey of the universe. This survey will add new partners and undertake new research missions, and will run through summer 2008.
Late last month the funding package for a new, three-year venture called the Sloan Digital Sky Survey II (SDSS-II) was completed, led by the Alfred P. Sloan Foundation of New York City, the National Science Foundation (NSF), the U.S. Department of Energy and the member institutions.

In the Standard Model, Quantum Chromodynamics (QCD) is the theory
describing strong interactions between objects of color charge.
Hadrons, such as the proton and neutron, are colorless particles
made up of strongly-interacting constituents.
The heaviest known hadrons contain a bottom or b quark.
Λb (pronounced "Lambda sub b") and Bs
("Bee sub s") are important
examples of such b hadrons.
The masses of these hadrons are determined by the mass of their
constituents and, very importantly, their interactions.
Masses of hadrons in systems bound by the strong force are the
equivalent to spectral lines in atoms bound by the electromagnetic
force. Thus the study of hadron masses infers details of the strong
A comparison between measurements of the masses and
predictions represents an important test of QCD.
Currently the experimental precision is considerably better than
theoretical calculations, but recent numerical advances are expected
to improve on the accuracy of the predictions.
At CDF b hadrons are reconstructed from their stable charged decay
products that leave ionization hits in the large tracking chamber
(outer radius 1.4m). The tracking chamber is situated inside a
magnetic field, that bends the trajectories of charged particles,
allowing their momentum to be measured.
Relying on this well calibrated device, CDF researchers have
accomplished the most precise measurements of b hadron masses to date.
The Λb and Bs masses are measured about
5 and 3 times better than the existing world averages.

LBNL, measured b hadron masses for his thesis and his advisor, Christoph
Paus, Professor at MIT.|
