Kestrels Can Soon Call Fermilab Even Nicer Home
Bill Wickenberg (left) and volunteers Bob Mathieu and Evalyn Campbell display one of the several American kestrel nest boxes to be located onsite.
The American Kestrel, one of the most common raptors found in North America,
American Kestrel
is a small reddish-brown falcon that thrives in several different habitats, including the woodlands and open fields of Fermilab. Soon lab kestrels will find nearly half a dozen nest boxes onsite where they can roost and raise their young this summer.

Kestrels are currently known to nest onsite in several locales, mainly under the eves of buildings. Local residents Bob Mathieu and Evalyn Campbell, who were already volunteering with Accelerator Division building manager Bill Wickenberg to help maintain the lab's 50 bluebird nest boxes, soon took notice of these colorful raptors. Mathieu asked if kestrel nest boxes could be put up at the lab as well, and over the winter, built several of them. Wickenberg and the volunteers have been careful to choose nest box locations away from where current kestrel nests exist, to avoid disturbing the birds.

The volunteers have already installed one kestrel nest box and installation of the others is in progress. "It's a slow process," explains Wickenberg. While scouting potential sites for boxes, they also must keep in mind things like the fall prairie burn schedules and possible kestrel territorial ranges. Nonetheless, the volunteers are optimistic about providing the new nest boxes. "My family moved to Warrenville in 1935, when it was 300 people, and this was all farmland," says Mathieu. He recalls seeing kestrels, mockingbirds, bluebirds, red-tailed hawks, and Cooper's hawks, in the area. "As far as kestrels interfering with or eating other birds, I've never seen them do it," he says. "Their main diet is mice and insects."

The Future of Digital Data
Over the last few decades, advances in

information technology have led to a fundamental change in research and education, and digital data collections are at the heart of this change. These collections are rapidly multiplying in number and increasing in size, and their management, preservation and use was the focus of the "Expanding Universe of Digital Data Collections" symposium at the 2006 American Association for the Advancement of Science Annual Meeting.

A novel search for long-lived new particles with DZero
Simulation of the production of a pair of neutral, long-lived particles with the subsequent decay of one of them to two muons and a neutrino within the Dzero central tracking region. (Click on image for larger version.)
Many of the greatest advancements in our understanding of particle physics have come from unexpected discoveries of new particles. For this reason experiments at Fermilab often look for the unknown. The DZero experiment has recently expanded its abilities by looking for low-mass, neutral, long-lived particles decaying to two muons. Such particles could be signals for supersymmetry and also possibly explain an intriguing, unexplained, and similar signal from NuTeV.

To search for long-lived particles, DZero fits pairs of muons to a common vertex (assumed to be the decay position of a hypothetical particle) and measures the distance from the point of the primary interaction. This separation is a measure of a particle's lifetime. Previous analyses used decays which have millimeter separation, while for this analysis, we search for decays at least 5 centimeters away from the primary interaction. The "K-short" meson is an example of an already known low-mass particle with long lifetime that decays within the detector to two pions. By studying K-short mesons we demonstrated our ability to reconstruct neutral particle decays at centimeter displacement.

DZero finds no muon pair events with a vertex in the search region. This result is consistent with background expectations. Together DZero and NuTeV rule out at least one explanation of the NuTeV excess as a signal of supersymmetry.

Above: Todd Adams (Florida State University) worked on this analysis. Below: Leo Bellatoni, Paul Rubinov and Jadwiga Warchol are members of the team working on an upgrade of the analog front end readout boards (AFE-IIt) for the DZero fibre tracker. This upgrade will be essential to ensure the continued excellent performance of the DZero tracking system at the very high luminosities expected in Run 2b of the Tevatron.

Particle Physics Workshop,
Live from Italy

The 20th anniversary of the annual particle physics workshop, Les Rencontres de Physique de la Vallee d`Aoste, will be held at La Thuile, from March 5 to 11. A special anniversary session will run from 10:00 to 11:30 a.m. and from 4:00 to 6:00 p.m. (local Italian time) on Monday, March 5. The distinguished speakers will be Rocky Kolb, Carlo Rubbia, Roberto Petronzio, Samuel C.C. Ting, Sheldon Glashow and Alvaro De Rujula. The titles of their talks can be found in the preliminary program at the conference web site. Streaming video will be available here.
