Yesterday's issue of Fermilab Today was sent out late due to technical problems with Fermilab's listservs. Thanks to the Computing Division, the problem was fixed yesterday morning. Fermilab Today appreciates your patience.

EPP2010 Meeting This Monday
UEC Chair William Trischuk recently sent this letter to Fermilab's Users to announce the upcoming EPP2010 meeting. An agenda for the meeting is available online.

Dear Fermilab Users,

The National Research Council is organizing a decadal study of our field this year. They have formed a committee EPP2010 of 22 members, approximately half from the field of particle physics, and half from outside. The committee has been charged with placing experimental particle physics in the context of the national basic research program, communicating its value and excitement to other scientific

fields, government agencies, and the general public. The commitee has also been charged with presenting a credible future for the field over the next fifteen years.

The committee has met twice already. It will meet again at Fermilab on Monday, May 16. At that meeting, the committee hopes to improve its understanding of the international nature of particle physics, both for truly global projects like the International Linear Collider and projects like the Proton Driver. Ian Halliday (PPARC), Yoji Totsuka (KEK) and Albrecht Wagner(DESY) will join Mike Witherell and Pier Oddone in making presentations to the committee. The meeting will also include an open microphone session organized by the APS/DPF Executive.

The committee is interested in the opinions of the community both through personal contacts, for example during breaks in the meeting at Fermilab, and from letters. Examples of the questions they have posed so far can be found online. Input received at epp2010@nas.edu will be distributed to the whole committee for discussion.

I encourage all members of the Fermilab community to attend the meeting on May 16 and send your opinions to the committee.

William Trischuk
UEC chair

Jack Mateski Retires But Hopes to Keep Hands In
Particle Physics Department's Joseph "Jack" Mateski retires today after nearly 24 years at Fermilab, primarily working with scientists and engineers to design detectors for DZero. "And it is a fun job, I tell you," said Mateski, a broad smile on his face. "I enjoy this kind of work, and wouldn't have stuck around if I didn't. You should enjoy your work." The Joliet, Illinois native worked at Argonne National Laboratory for a number of years before PPD's Donald Tousignant helped him land a job at Fermilab. Mateski is optimistic that his time at Fermilab isn't completely over. "I hope they call me so I can keep my hands in at the lab," said Mateski.

Fermilab has been a family affair for Mateski. All but one of his four children participated in high school co-op programs and worked during the summers with their father. Mateski and his wife Kathy will celebrate their 41st wedding anniversary on May 23. He plans to relax, work around the house, fish, travel around the country, and take his grandchildren to area parks. Every Thursday he and the Fermilab Golf League travel to Phillips Park in Aurora to play 18 holes. Mateski, who refers to younger, salt-and-pepper-haired engineers as "kids," will miss the people at the lab the most. "There are a lot of brilliant people here," said Mateski. "I think that we have come up with innovations that have helped humanity."

Retiring Igor Churin Bids 'Adieu' to Friends at Lab
Igor Churin, a mechanical engineer for the Particle Physics Division, will retire tomorrow after 11 years at Fermilab. Churin emigrated to the United States 18 years ago from the Soviet Union because, he says, "I hated it. It was dead then, rigid and very conformist." Here at Fermilab Churin has had the opportunity to design calorimeters for the Superconducting Supercollider, KTeV, and CMS. Working with three other Russian engineers, Churin designed the CMS calorimeter that has more copper than the Statue of Liberty. In a swords-to-plowshares irony, part of the calorimeter was made at a former nuclear weapons manufacturing site in Russia, and another part was made from old

artillery shell casings. Churin is currently designing a pixel detector for the LHC made of lightweight carbon fiber.

Churin will miss the open environment of Fermilab, which "includes all the friends I have made here." He and his wife Anna have been married 38 years. They have two grown children and three "adorable" grandchildren, who live next door to their grandparents. Churin will spend his retirement playing with his grandchildren, but he also has plenty of work to do around the house when he is not listening to classical music, taking photographs, traveling (his favorite National Park is the Boundary Waters in Minnesota), gardening and reading.

Fermilab Result of the Week
Precise Prediction of Particle Mass, Confirmed by Experiment
Theory Result

For decades theoretical physicists have tried to compute from first principles the properties of hadrons, a family of subatomic particles that includes the proton and neutron. The main obstacle was the intractable nature of quantum chromodynamics (QCD), the modern theory of how quarks bind to form hadrons. Now scientists have confirmed the validity of a new numerical approach, proposed in a recent paper [Phys.

As an application of the new method, a team of physicists from Glasgow University (UK) and Fermilab calculated the mass of a particle called the Bc meson, which consists of a bottom quark and a charmed antiquark. The Bc is a rare particle produced in collider experiments. Until recently, observations gave poor measurements of its mass.

In the May 6 issue of Physical Review Letters, the

for larger version.)
Glasgow-Fermilab theorists predict the mass of the Bc to be 6304 MeV, with a margin of error of about 20 MeV, or 0.3 percent. After the paper was submitted on November 19, 2004, one of the Tevatron collider experiments announced a new mass measurement, yielding 6287 MeV with an uncertainty of 5 MeV. The result confirms the theorists' prediction. Since the numerical techniques can be used to compute other hadron properties, they are expected to aid experimenters searching for new quark interactions.
