Oddone stresses vital program, promotes positive work culture

Fermilab director Pier Oddone covered a multitude of topics in an all hands meeting on Sept. 21.

Focusing on Fermilab’s strong future programs and fostering a positive work environment were two themes of the presentation that Fermilab Director Pier Oddone gave to employees in all-hands meeting Wednesday. The presentation covered four subject areas, including an overview of the laboratory’s future after the Tevatron, recent Congressional budget actions, results from the Employee Advisory Group survey and changes in health insurance costs.

Life after the Tevatron

Commenting on the Tevatron shutdown event planned for employees and users on Sept. 30, Oddone reminded the laboratory that this is the beginning of a new chapter in Fermilab’s history.

“We have constructed a very exciting program, a very vital program over the last few years,” Oddone said.

Oddone went through that program, highlighting Fermilab’s contributions to the LHC and the shift from the Energy to Intensity Frontier. He explained the science of key neutrino and muon projects and experiments, such as Mu2E and the proposed Long-Baseline Neutrino Experiment and Project X.

“What is most important to us is that we contribute to the global picture with facilities that are at Fermilab that are part of the U.S. program,” Oddone said. “We have, because of the work done by all of you and because of my predecessors, very competent machines that remain even after the Tevatron.”

In Brief

ARRA website updated

The American Recovery and Reinvestment Act (ARRA) helped fund six general infrastructure projects at Fermilab over the past two years. The projects consisted of expansions and upgrades throughout the lab. Upon the completion of each project’s construction, the project teams celebrated with a plaque ceremony. Please visit Fermilab ARRA website to learn more about these projects.

Special Announcement

Party for CDF contributors

All past and current CDF collaborators as well as those who helped design, build or operate the detector are invited to a CDF end of detector operations party on the evening of Friday, Sept. 30. For more information or to RSVP please contact Dee Hahn.

Fermilab faces life after the Tevatron

From Nature, Sept. 21, 2011

Like an old and celebrated race track, the giant particle accelerator known as the Tevatron is down to its final laps.

Shortly after 2 p.m. on 30 September, with reporters watching by video link from a nearby auditorium, an operator at the Fermi National Accelerator Laboratory (Fermilab) in Batavia, Illinois, will divert the final bunches of protons and antiprotons speeding around the Tevatron's 6.3-kilometre ring, sending them barrelling into a solid metal block. The experiment that ruled high-energy physics for more than 25 years will then be over, its funding expired.

The shutdown will provide an occasion to dwell on the Tevatron's past successes, but it also marks Fermilab's transition to smaller and lower-profile experiments that explore different kinds of physics.

Fermilab looks ahead as shutdown of Tevatron looms

From Kane County Chronicle,
Sept. 21, 2011

Using superconducting magnets chilled to minus 450 degrees Fahrenheit – as cold as outer space – Fermilab’s Tevatron accelerator moves particles at nearly the speed of light.

“It’s a modern marvel, really,” said Rob Roser of Elburn, who has been working on the CDF, or Collider Detector at Fermilab, experiment at the Tevatron since 1994.

The Tevatron has been helping scientists better understand our universe since starting operations in 1985. But at 2 p.m. Sept. 30, a switch will be thrown that will cease beam operations to the two experiments at the Tevatron – CDF and DZero, Roser said.

Casting a wide net

To search for unanticipated physics, you need to make sure you do searches that make the minimum number of assumptions of what new physical phenomena might look like.

I give a lot of public lectures. I speak about DZero’s attempts to find the Higgs boson or the search for supersymmetry. Most of the time, the talks go off without a hitch. But every so often, a hand will go up, and I’ll get hit by a thoughtful question. The words change from person to person, but essentially the question is “Excuse me Dr. Lincoln. You’re telling us about all these particles you guys are looking for. But what if the thing to be discovered is something nobody’s ever thought of? How do you know you’re not overlooking something totally unexpected?”

And this is a most excellent question. The history of science is replete with observations that weren’t predicted. As Isaac Asimov, the American author and biochemist, is reported to have said, “The most exciting phrase to hear in science, the one that heralds new discoveries, is not ‘Eureka!’ but rather ‘That's funny...’”

Luckily, this insightful question has an answer. DZero completed a Model Independent Search, guided by a single assumption, which is that new phenomena will most likely be found in the most violent collisions. In essence, we made thousands of plots, consisting of 117 different combinations of electrons, muons, jets, etc., and compared them to the predictions of the Standard Model.

The idea is that if there were new physics to be found, it would show up in one or more of these plots. To verify that the idea works, we even “re-found” the top quark, by comparing our data to Standard Model calculations from which top quarks were removed.

This approach is generally not as effective at any specific search as one motivated by a theoretical prediction. However, it casts a wide net, to ensure no new physics fish slips through. If we see something, a more focused study is in order.

Of the 117 different combinations of particles, only two exhibited any significant difference from the Standard Model. Because these two combinations are known to be difficult to model correctly, we cannot claim we’ve discovered something. But we have provided a direction for more directed studies. If there are any fish to be found, DZero will catch them.

—Don Lincoln
