From symmetry magazine

symmetry available online

The latest issue of symmetry magazine is now available online, featuring articles on faster-than-light neutrinos, the Tevatron's legacy, a groundbreaking W mass measurement and much more. Hard copies will be delivered to subscribers in the next couple of days and will be available in the atrium of Wilson Hall on Friday as well.

In Brief

Fermilab releases long-range accelerator schedule

The Program Planning Office released the laboratory's new draft schedule for accelerator experiments recently. The new schedule comes following the decision on the schedule for the upcoming long accelerator shutdown.

The new proposed schedule, which stretches to 2015, shows a shutdown of the accelerator complex to begin at the end of April, and last for about eleven months for an upgrade of the proton source and change of the configuration of the NuMI beam for NOvA and other NuMI experiments.

Both the long-range schedule and a two-year, near-term schedule are available on the Fermilab program planning website.

Grand illusion: Are we living in a 2D world?

From the Medill newsroom at Northwestern University,
Feb. 14, 2012

Imagine that the universe is a hologram, that everything is 2D, not 3D, and that your own vision is a part of a grand illusion. Now imagine a dinky trailer on the prairie and a band of physicists pondering the universe inside, puzzling out a way to prove or disprove whether the world is flat.

"You get a Ph.D. and you work in a trailer," said Tona Kunz, senior editor of the communications office at Fermilab, "But he loves it."

"He" is Chris Stoughton, astrophysicist and one of the leaders of quite possibly the quirkiest experiment at Fermilab. Stoughton and a crew of physicists and college students are in the midst of constructing the Holometer, essentially a laser beam that can measure data of gravitational waves at the smallest possible scale. The goal is to determine whether the universe is a hologram.

It's a test of Fermilab astrophysicist Craig Hogan's theory, which sprang up when he spoke with a fellow scientist who detected "noise" in gravitational waves that he couldn't explain. The Fermilab project is mining the same field as string theory, a murky and complex field of physics theorizing how gravity and particles may interact. Stoughton described it as reconciling the very big theory of the universe -general relativity, which relates to gravity - with the very small quantum mechanics.

In what can be called a seminal test of string theory, the Holometer will measure gravitational waves at a scale smaller than any technology of its kind has yet been capable of doing. When looking at waves at such a small scale, quantum mechanics and general relativity no longer apply, making it possible to see whether the universe is flat and everyone's eyes are playing tricks on them.

Obama budget plan provides little for Fermi, Argonne

Feb. 14, 2012

Fermi National Accelerator Laboratory is facing setbacks in new research programs now getting under way after last year's federal budget cuts forced the shutdown of the Tevatron particle accelerator, its primary mission for the last three decades.

While high-energy physics research was trimmed only 1.8 percent in President Barack Obama's fiscal 2013 budget proposal on Monday, Batavia-based Fermilab would lose about $30 million of its current funding of $395 million, a cut of nearly 8 percent.

Argonne National Laboratory, another of the Chicago area's crown jewels in scientific research, would see an increase of less than 1 percent in its 2013 budget, bringing the Darien-area facility to almost $409 million, still about $8 million below where it was in 2011, according to the president's detailed budget proposal for the Department of Energy, which funds both labs.

While the White House budget request is only the first step in a long process to get congressional approval of next year's funding, it puts the Illinois delegation's longtime efforts to score more funding for the labs in a relatively poor field position this year.

CDF at the cosmic frontier

The CDF results represent the worlds best limits on spin-dependent dark matter below a dark matter mass of 200 GeV/c2.

There is more than five times as much dark matter as there is visible matter in the universe, according to our current understanding. Incredibly, this dark matter completely determines the large-scale structure of the universe, forming pockets of mass that gravitationally contain clusters of galaxies. How can a particle with such a strong effect on nature be so elusive that it is able to hide in everything from galaxies to the living rooms of unaware physicists?

Many popular theories predict a relatively heavy dark matter particle of more than 100 GeV/c2. But results from several direct-detection experiments have found interesting hints of dark matter at a mass about a tenth of predicted amount. A recent paper from Fermilab theorists suggests that the Tevatron could be particularly sensitive to detecting low-mass dark matter produced from the energetic proton-antiproton collisions.

Physicists at the CDF experiment, in collaboration with the authors of the Fermilab theory paper, developed an analysis to search for dark matter based on this work. Though no evidence for dark matter was observed in this analysis, the results are impressive. The CDF search sets the world's best limits for spin-independent dark matter at very low mass, as well as the world's best limits for spin-dependent dark matter up to an incredible 200 GeV/c2. This novel analysis clearly demonstrates the power of collider experiments to contribute to the hunt for dark matter, even if it, unfortunately, did not find evidence for dark matter.

Experiments such as COUPP and DAMIC, along with these new results from CDF, demonstrate the formidable effort at Fermilab in hunting for the dark matter. The search continues.
