Federwitz keeps employees on task and laughing

Jody Federwitz, of PPD's Mechanical Engineering Department, is a 22-year Fermilab veteran.

What people in the Particle Physics Division Mechanical Engineering Department love the most about Jody Federwitz is her sense of humor.

"Jody is always professional, with an eye for details and ways to make improvements, someone you can count on to start and finish a project," said Elaine Phillips, of PPD's Support Services Department. Yet she still brings joy to the work day at Fermilab, Phillips added.

When Federwitz, an administrative assistant, arrived at the laboratory in 1987 people had just started using computers on a daily basis. Her job has included training PPD employees using the laboratory's Procard database and warning co-workers about rogue geese.

Federwitz always had a goal to work at Fermilab. She and her husband, Glenn, who works for ES&H in AD, moved to Batavia from Wisconsin when he was hired by the laboratory in 1977. She waited until their two daughters were in school before applying to Fermilab.

Over the years Federwitz has worked in the areas of safety, cryogenics, electrical and mechanical engineering as well as with the U.S. Particle Accelerator School based at Fermilab. Federwitz said her 22 years feels like only about five. Federwitz sees how physics can affect people's everyday lives.

"The research done here has given us medical imaging, cancer therapy, supercomputing and there's a lot more yet to be discovered," she said.

She has been a member of the Auditorium Committee since 2000. Her fondest memory is working the open house in 1997 because she was able to show the laboratory's neighbors around. She said it was hard work but rewarding.

"When I retire I hope people will say that I made them laugh," Federwitz said. "But I'll also have made sure they got their paperwork in on time."

Fermilab physicist George Gollin wins Guggenheim Fellowship

George Gollin

From University of Illinois at Urbana-Champaign News bureau, April 8, 2009

CHAMPAIGN, Ill. - Two University of Illinois physics professors, George Gollin and Laura Greene, and visiting scholar Jabari Asim have received 2009 Guggenheim Fellowships.

They were among 180 artists, scholars and scientists to be selected in the John Simon Guggenheim Memorial Foundation's 85th annual competition. Winners are chosen on the basis of their "stellar achievement and exceptional promise for continued accomplishment," the foundation said in its April 8 awards announcement.

The five greatest mysteries of antimatter

From New Scientist, April 22, 2009

It was not so long ago that we were hearing how CERN's Large Hadron Collider would produce planet-destroying black holes. Now Dan Brown's blockbuster, due to hit the big screen next month, provides us with another supposed danger emanating from the particle physics laboratory near Geneva, Switzerland: antimatter, the seed of a weapon of unsurpassed destructive power.

While Brown's take on antimatter is fictional, the stuff certainly isn't. We see its signature in cosmic rays, and it is routinely made in high-energy collisions inside particle smashers the world over. In hospitals, radioactive molecules that emit antimatter particles are used for imaging in the technique known as positron emission tomography.

Brown was right about one thing, though: if you want answers to the burning questions of antimatter, CERN is the place to go.

Fermilab Result of the Week

CDF reaps double reward with double W measurement

The recent CDF result, shown in red, is the most precise ever of the WW production cross section. CDF reaps double the reward since the measurement also helps to precisely constrain the backgrounds of searches for a Higgs boson decaying to two W bosons.

Two is better than one... at least for CDF scientists. They took a break from their search for the Higgs boson to study what they consider a background -- the production of two W bosons that didn't come from the decay of a Higgs boson. In the process, they made the world's best measurement of how often these double Ws are produced in proton-antiproton collisions.

The W boson is one of two subatomic particles that mediate the weak force. The other particle is the Z boson. Double W production is an important Standard Model process to understand. But the WW final state is also interesting because of which particles might decay into it. A Higgs boson, in particular, might help explain how particles gain mass and it would decay primarily into two W bosons. To find the signature of a Higgs boson to WW decay, scientists must first know very precisely how often double Ws are produced directly from other processes. That's the goal of this measurement.

By selecting from the same data and applying the same advanced analysis tools used for the Higgs search, CDF scientists searched for WW events where each W decays to a lepton (electron or a muon) and a neutrino. CDF scientists separated the true WW events from backgrounds using the measured information from the leptons and the missing energy, caused by neutrinos which escape the detector without interacting. Their measurement of WW production agrees well with theoretical predictions.

With this new, more precise measurement of WW production, CDF scientists demonstrate that they understand and can predict well the largest background for searches for a Higgs decaying to two W bosons. This result also validates that the advanced analysis tools used in the Higgs search work well when CDF scientists apply them to a known process. Next step: find the Higgs.
