New Perspectives from Graduate Students
New Perspectives 2004
New Perspectives 2004
(Click on photo for
larger version.)
Save the date for New Perspectives 2004, the annual conference organized by the Graduate Students' Association for all Fermilab graduate students. On Thursday, June 3 and Friday, June 4, graduate students will have the opportunity to attend talks and view students' posters that illustrate the broad range of research being conducted at Fermilab. In addition to students' talks from CDF, DZero, MINOS, MiniBOONE and FINeSSE, Nobel Laureate Leon Lederman and David Hertzog of the Brookhaven g-2 experiment will speak at the conference.

Posters will be on display in the Atrium of Wilson Hall for both days, with a wine and cheese reception from 5:00 p.m. - 7:00 p.m. on June 3. The three best posters will be awarded prizes, which will be presented in remembrance of George Michail. Talks will take place from 9:00 a.m. to 5:00 p.m. on June 4 in Curia II. The poster prize-winners will be announced at the end of the day, before the conference comes to a close with a barbecue at the Kuhn Barn at 6:00 p.m.

If you are a graduate student who would like to present at New Perspectives, there is still time to submit an abstract for a talk or a poster by emailing gsa_officers@fnal.gov this week. More information about the conference and a form for free registration is available online.

Electrical Safety Month Profiles
In connection with Electrical Safety Month, Fermilab Today offers a series of profiles recognizing Electrical Coordinators at Fermilab. This is the final article in the series.
Electrical Safety Manager Leon Beverly
Leon Beverly has been supervising electricians at Fermilab for 35 years. He began his career at the lab on May 20, 1968 as a linac technician, and supervised electricians for the first time in 1969 when the installation of equipment started in the brand-new linac building. Since then he has worked on electrical engineering design and installation for many experiments in

the fixed-target area. Now a senior engineering associate and head of the PPD Site Department and the floor manager for the MINOS installation, Beverly has seen the awareness of safety at the lab increase over the past three decades.

"Safety and your work go hand-in-hand; you can't separate one from the other," said Beverly. "People have always been responsible for their own safety. What's changed is the level of daily safety awareness. With all the training programs available now and the adoption of Integrated Safety Management, there is a lot more awareness of safety protocols."

In his 36 years at Fermilab, Beverly has served several times on the electrical safety subcommittee and once on the subcontractor safety subcommittee. He has also participated in the electrical portions of operational readiness reviews for multiple experiments, including KTeV and DZero Run I.

Accelerator Update
May 24 - May 26
- Operations established one store during this period of time that, added to an existing store, provided approximately 31 hours and 14 minutes of luminosity to the experiments.
- The TeV set a new record with an initial luminosity of 68.92E30
- The Recycler resumes stashing antiprotons

Dark Doings
Ever since 1998, Robert Caldwell has been obsessed with something dark and repulsive. He spends nearly every waking moment trying to comprehend a mysterious entity that may be undermining gravity and pulling everything apart, making the universe expand at a faster and faster rate. This presumed force, sometimes called dark energy, might ultimately rip apart every object in the cosmos, from the tiniest of atoms to gargantuan clusters of galaxies. "It's both fascinating and terrifying," says Caldwell, a cosmologist at Dartmouth College in Hanover, N.H.

DZero Swings Right in Top Quark Analysis
According to standard theory, W bosons from decays of top quarks are supposed to spin counteclockwise relative to their motion (negative helicity), and not clockwise (positive helicity). This can be checked at CDF and DO in Run II of the Tevatron. A new proof for the ability to measure such parameters has been developed at DO by Florencia Canelli (UCLA), Juan Estrada and Gaston Gutierrez (Fermilab), and was the basis of Florencia's PhD thesis at the University of Rochester. (Click on image for larger version.)
The observation of the top quark in 1995 at CDF and DZero opened new ways of probing subtleties of the Standard Model. Although the predictions of the Standard Model have thus far had remarkable success, new interactions are expected to appear near Tevatron energies. With the top quark being the heaviest of all elementary particles, it has been argued that its interactions might offer first experimental evidence for the limitations of the theory.
Scott Snyder
This analysis was
based on data
selected by Scott
Snyder from Brook-
haven - who has also
contributed greatly to
DZero's software.
For example, the Standard Model predicts that top quarks decay to W bosons that spin just like left-handed screws - a property called negative "helicity".

Looking for any right-handed helicity in such W bosons is a way to find deviations from theory. In a new analysis, similar to that developed for measuring properties of the top quark (especially its mass - see Fermilab Today, January 15, 2004), DZero has shown that its approach is viable. Although the extracted value of the helicity is still imprecise, with more data from Run II, a significant test of the standard model will be forthcoming. In the meantime, DZero is delighted that this new method will provide an excellent way of making this important measurement.

A symposium in honor of Alvin Tollestrup and his contributions to Fermilab will be held Tuesday, June 1 at 3:00 p.m. in One West. All are invited to attend the symposium, where Fermilab's Vladimir Shiltsev will discuss the Tevatron, Giovanni Punzi from INFN Pisa will speak on the CDF silicon vertex trigger, and James Annis from Fermilab will discuss the dark energy survey project. Refreshments will be provided at the conclusion of the talks.

"We're using Alvin's 80th birthday as a way to honor him and all the good things he's done for the lab," said Fermilab physicist Peter Limon.

Hadron Collider Physics 2004
Deadline for Discounted Registration Fee is May 31
The 15th Topical Conference on Hadron Collider Physics will be at Michigan State University from June 14 to June 18. Register before May 31 and receive a discounted registration fee. This conference is of particular interest to the Fermilab Community because it covers the research being conducted with the Tevatron. Support is available for graduate students who would like to attend the conference.
