All Hands Meeting Friday 1:30 p.m. Ramsey Auditorium
Pier Oddone will announce an important new appointment at the laboratory at an All Hands meeting on Friday, January 27 at 1:30 p.m. in Ramsey Auditorium. He will also discuss the state of the laboratory and the on-going analysis of the laboratory organization, with plenty of time for questions and answers. Overflow seating will be available in One West, with audio and video provided.

They Came From an Extra Dimension… or Two
Bogden Dobrescu
Theoretical physicist Bogdan Dobrescu finds the top quark "a great tool" to search for extra dimensions.

Although we seem to live in three spatial dimensions, physicists study the possibility of other dimensions which are hidden because they are too small to see. "Particularly interesting are the so-called universal extra dimensions, in which all known particles can propagate," said Fermilab theoretical physicist Bogdan Dobrescu. "If universal extra dimensions exist, then for each of the elementary particles we know, there would be a whole family of heavier particles with similar properties, called Kaluza-Klein modes."

New predictions for the experimental signatures of universal extra dimensions have been made this week in a paper titled "Resonances from Two Universal Extra Dimensions," which is now available on the hep-ph archive . Dobrescu authored the study with two former Fermilab postdocs, Gustavo Burdman (University of Sao Paulo in Brazil) and Eduardo Ponton (Columbia University). They spent more than a year computing the masses of these Kaluza-Klein modes and all their interactions. The researchers predict that when these heavier particles decay, they produce a very specific signal: a top quark and an anti-top quark, with energies matching the mass of the Kaluza-Klein mode.

"It's interesting that now, ten years after the top quark discovery, we find that the top quark is a great tool in the search for something as exciting as extra dimensions," said Dobrescu. "Two universal extra dimensions would explain certain basic facts about nature, including the stability of the proton, the origin of dark matter, and the existence of three 'generations' of quarks and leptons." Dobrescu points out that this is a particularly thrilling time at Fermilab. "Our wild theoretical ideas about physics at the energy frontier are just about to be tested experimentally by the DZero and CDF collaboration," he said. Dobrescu, who was promoted to Scientist I in October 2005, anticipates that the Large Hadron Collider (LHC) scheduled to begin operation at CERN in 2007 will further test the existence of extra dimensions.

Science on a Shoestring

Sometime next year, the world’s attention will focus on Geneva, where scientists will switch on the Large Hadron Collider, an underground atom smasher more powerful than anything to come before it. By bashing protons together at ultra-high speeds, researchers hope to get closer to discovering the origins of the universe — perhaps leading to breakthroughs in our knowledge of matter and energy that will rival Einstein’s theory of relativity.

One milestone sure to occur when the LHC boots up: The United States will no longer be the leader in high-energy physics research.

Director's Corner
Yesterdy I spent a couple of hours in
Pier Oddone
Pier Oddone
discussions with EPP2010, the committee of the National Academy that has been charged by DOE and NSF to give advice on the future program for Particle Physics. I was very thankful to the committee and its chair, Professor Harold Shapiro of Princeton University, for the invitation to join the committee. It gave me the opportunity to present and discuss in detail our ideas for the future program at Fermilab and to answer questions on the issues that have arisen in the committee's mind in connection with our plans. I was very impressed with the depth of the committee's questions and the level of the discussion. It is clear that in the many months that EPP2010 has been at work, the committee has reached a deep level of understanding of the strategic issues of our field and the difficult decisions that we confront. It was also clear to me that there is a genuine feeling of support and enthusiasm for the field and that the committee is exercising great care in reaching its recommendations.

As I have mentioned in a previous column, the recommendations of this committee will be critical for the future development of particle physics in our country since the recommendations will represent a broader view and more impartial advice than the usual advice we get from our own expert committees. Advice that comes from our own community has been likened to asking the teamsters if they need more trucks. Of course they do!

In my visit with Professor Harold Shapiro in Princeton last Tuesday I learned that the committee will finish its report in March and then the report will go through the usual reviews within the Academy before it is released. It will be an exciting moment when the report is finally unveiled and we learn the recommendations of EPP2010!
