Carlos Gonzalez Rides Into A New Mexico Sunset | ||
| ||
|
Carlos Gonzalez, a senior electric technician from PPD, retired yesterday after
working at Fermilab for more than 29 years. The 55-year-old Chicago native spent
most of his time working on the Main Ring RF systems until he moved to the
Sloan Digital Sky Survey at Apache Point Observatory, New Mexico.
His favorite work memory is the beginning of SDSS. "It was very exciting to
be there at the telescope's first light, to turn it on and actually see
the stars," said Gonzalez.
Gonzalez plans to stay in New Mexico. "When most people retire they buy an
RV and drive to Florida or Arkansas and find a home," he said. "I'm already
here in New Mexico!" He plans to spend his retirement riding horses
and motorcycles, driving his 1986 El Camino Super Sport, shooting his guns,
and working at the High Rolls Volunteer Fire Department.
He recently became a member of the Red Knights, a motorcycle club for
retired and active firefighters.

Fermilab Arts Series Presents: Michel Lauziere Limited Tickets Available | ||
| ||
|
The Fermilab Arts Series presents "Michel Lauziere: Master of the Unusual"
on Saturday, April 16 at 8:00 p.m. in Ramsey Auditorium. Due to its
popularity, only a limited number of tickets are still available for this show.
Lauziere's creative performances feature impressive musical and visual effects, earning him appearances on major television shows and on stages around the world. Lauziere currently performs on many networks including Showtime, Comedy Central and HBO.
A man of many talents, Lauziere is a visual humorist, a
fantasy artist, a musician and, above all, a creative performer who gains
personal satisfaction in capturing his public's affection. With his incredible
talent and imagination, he can make music out of anything.
Bring the whole family for a night of
great fun this Saturday at Fermilab.

FYI: AIP Bulletin of Science Policy News, April 13, 2005 Orbach Offers Perspective on FY2006 DOE Science Request Last week's meeting of the Fusion Energy Sciences Advisory Committee included a presentation by Office of Science Director Ray Orbach. While many of his comments concerned the fusion program, his remarks could be applied to most of the programs in his office. Said Orbach of the FY 2006 budget request: "we've had to make difficult choices."
Orbach described the Administration's determination to cut the deficit in half by 2009 (estimated to be $427 billion this year) as the backdrop against which the FY 2006 budget should be viewed. Non-security discretionary spending would be cut by almost 1% under the president's request. Orbach acknowledged that this downward pressure had impacted the FY 2006 request. He added that the Office of Science "had not been treated badly in this budget [request]" or in the funding projections for the next four years.

In Pursuit of Beautifully Enhanced Higgs Bosons | ||||
| ||||
|
Since the Higgs boson is responsible for the mass of fundamental particles and would complete
the Standard Model, its discovery would be an extremely exciting
event.
Previous Results of the Week form DZero have highlighted searches for the Standard Model Higgs. That may not be the end of the story. The Standard Model has a number of serious esthetic and theoretical shortcomings. One extension of the Model, Supersymmetry or SUSY, which incorporates five Higgs bosons (three of which have no charge), neatly resolves many unattractive aspects of the Standard Model. The neutral supersymmetric Higgs particles can be recognized by their decays into beauty (or "b") quarks. The rate of Higgs bosons produced in association with b-quark decays may be enhanced by an as yet unknown and quaintly named SUSY parameter, tan(beta).
Experimentally, it is a major challenge to efficiently separate a Higgs boson decaying to b-quarks/jets from a number of overwhelming background processes. However the b-quarks have distinctive experimental signatures. Accurately predicting the rate of SUSY Higgs events at the Tevatron also represents a major theoretical challenge. Groups from Argonne, Brookhaven, and Fermi National Laboratories and Florida State, SUNY/Buffalo, and the University
DZero has searched for events containing b-quarks and compared the number seen to the number expected from these theoretical calculations. Since no signal events have been observed so far, large values of tan(beta) can be excluded depending on the specific SUSY model and assumed Higgs boson mass. Figure 1 (above) shows the limits as a function of a Higgs mass for two representative models. As more data are collected, the SUSY models will be severely constrained. Or, better yet, we may discover a Higgs particle markedly different from the one expected in the SM. Either way this beautiful SUSY Higgs search promises to be very exciting. | ||||
