In Memoriam : Cathy Voit, 63, Sr. Electronics Technician and Writer
Cathy Voit
Cathy Voit
Cathy Voit, who brought levity and wit to all her responsibilities at the lab for 26 years, died of a heart attack on November 24 at her home in Wheaton. She was 63.

A Senior Electronics Technician for the Accelerator Division, Voit was also co-leader of the Bible Study Group at the lab, and a member of the Fermilab Writer's Club. She received a degree in Communications in 1994 at the age of 54, and had been writing a novel about an archaeologist exploring a volcano in Italy. "It was fun reading. She was very excited about it," said Bruce Worthel of Accelerator Division, former head of the writing group. "Her creativity was not an aspect as well-known" about Voit, said Teri Dykhuis of ES&H and a fellow Bible student. "But her sense of humor was her signature."

A memorial service will be held at 11 a.m., Saturday, January 17 at the Wheaton Wesleyan Church.

SC2003: Igniting Innovation
Supercomputing 2003
15th annual Supercomputing Conference in Phoenix, Arizona
Fermilab and SLAC presented a joint exhibit at the 15th annual Supercomputing Conference, Nov. 15-21 in Phoenix, Arizona, showing the role of advanced computing technologies at the high-energy physics labs. Featured projects included high-fidelity modeling of accelerators; GRID and data analysis techniques for Run II, Babar, and the LHC; advanced networking; and data storage. "The purpose is to get the message out that we do leading edge computing in our field," said John Urish of Fermilab's Computing Division.

The Fermilab-SLAC exhibit was one of nearly 220 displays for the 8,000 conference attendees. CD's Jeff Kallenbach noted, "This is our 4th year sharing an exhibit with SLAC. Besides highlighting leading-edge computing at the HEP labs, it gives us a chance to collaborate with SLAC on a unique project."

Fermilab's Education Office demonstrated QuarkNet's use of grid computing techniques in education, sharing data from cosmic air shower detectors placed in high schools. "We were pleasantly surprised with the interest generated by our small project, which seems to be the first education project to develop a website with access to a Grid portal for high school students," said Marge Bardeen, head of the Education Office. A group from BTeV added a live demonstration of a real-time cluster computing fault-detection methods. "Our visitors were surprisingly interested. That's always an upper," said Ruth Pordes of the Computing Division.

World summit urged to make science more available
GENEVA - Scientific information should be made more easily and freely available especially to researchers and others in developing countries.

That is one of the key messages that the scientific community is sending the World Summit on the Information Society (WSIS), which opens in Geneva, Switzerland, today (10 December).

Fermilab Result of the Week
Search for Leptoquarks with the CDF Detector
CDF
Preliminary limits from the CDF Run II searches for first generation leptoquarks. (Click on image for larger version.)
Following up on last week's DZero results in the search for leptoquarks, this week's results are from the other side of the Tevatron ring.

At CDF Run II, three analyses were completed by Summer 2003 to search for leptoquarks of first generation. The first analysis searched for pairs of electrons and quark jets; the second analysis searched for an electron, a neutrino and quark jets and the third analysis looked for two neutrinos ( experimentally detectable as missing energy) and quark jets.

These three searches show no evidence for the existence of leptoquarks. Therefore, CDF physicists calculated upper limits on their production rate and derived lower limits on their masses (see above plot).
If 1st-generation LQs exist, they must have a mass larger than 232 GeV/c2, 197 GeV/c2, 107 GeV/c2 assuming a branching fraction into a charged lepton and a jet

of 100%, 50% and 0% respectively.

A fourth analysis searching for leptoquarks decaying into muons and quark jets ( second generation leptoquark) is currently underway making use of a data sample corresponding to a larger integrated luminosity.

For the future CDF plans to search for leptoquarks decaying into third generation fermions and to update the current results with incresingly larger data samples.
