AAAS coverage

Editor's note: Symmetry magazine staff wrote a series of blog posts from the AAAS meeting. The following articles are a sample of the posts available on the symmetrybreaking Web site.

Hunt for the Higgs kicking into high gear

If the Tevatron experiments collect data through 2011, their chance of finding evidence for the Higgs particle is larger than 30 percent for most of the Higgs mass region of interest, 114 to 185 GeV/c2. A Higgs mass of 170 GeV/c2 already is excluded by the analysis of Tevatron data last summer (see plot below).

Researchers with the Tevatron experiments at Fermilab told fellow scientists and journalists not to count them out of the race to discover the Higgs boson.

“In the next few years, if the Higgs lives in the expected mass range of 114 to 185 GeV, we will most probably see evidence of its existence,” said Dmitri Denisov, co-spokesman of DZero and a Fermilab staff scientist, Sunday at the American Association for the Advancement of Science conference in Chicago.

The Higgs explains how particles acquire mass, and is the last, missing piece of the Standard Model, which explains matter and how it acts. Essentially, the Higgs is the last piece of a puzzle describing everything around the world, including ourselves, Denisov said.

While the Large Hadron Collider in Europe is the new, bigger kid on the high-energy physics’ block, Tevatron researchers said their smaller experiments bring a finely-tuned machine and a head start to the game.

It might take the LHC until 2011 or 2012 to reach the sensitivity needed to find the Higgs, said Jim Virdee, spokesman of CMS and a professor at Imperial College of London.

A first: String theory predicts an experimental result

The biggest criticism of string theory is that it doesn't make predictions that can be tested experimentally-a requirement for any solid scientific idea.

That's not true anymore.

At an AAAS session on Sunday, physicists said string theory is making important contributions to the study of two extreme forms of matter -one heated to trillions of degrees, the other chilled to near-absolute zero. In both cases the matter became a "perfect liquid" that ripples and flows freely, like water. String theorists analyzed the results by applying what they had learned from pondering how a black hole might behave in five dimensions. Then they went on to calculate just how free-flowing these liquids might be, predictions that the experimenters are using to guide the next stage of their work.

"It's really a surprising, I would say serendipitous, once-in-a-generation convergence of scientific communities," says Peter Steinberg, a nuclear physicist at Brookhaven National Laboratory and one of the organizers of the panel. "None of us saw this coming."

Cosmic mystery: High-energy invaders from space could signal a nearby pulsar, or perhaps dark matter

From Science News, Feb. 28, 2009

There's an air of excitement in the astrophysics community, created by a surplus of particles from space invading Earth's atmosphere.

Balloon flights high in the stratosphere over Antarctica detected electrons in numbers and energies much higher than what usually pours in from space, scientists on a project called ATIC reported in November.

About the same time, a separate report from Milagro, a ground-based detector near Los Alamos, N.M., described two unexpected patches of high-energy protons in the sky. A review of seven years of Milagro data revealed an unusual distribution in the energies of these cosmic rays.

Director's Corner

For us, passage of the American Recovery and Reinvestment Act was the big news of the week, the year and--barring discovery of the Higgs--the decade. It makes a large investment in science and technology to support not only the creation of jobs but the nation's competitiveness. The investment in the DOE Office of Science contained in the act is $1.6 billion. Overall the act invests significantly in all the science agencies and in education.

While the specifics are still being worked out by DOE and the Office of Management and Budget, we hope for major advances here at Fermilab: funding to accelerate NOvA; to build the infrastructure for developing, prototyping, testing and industrializing superconducting accelerator components; and for the immediate construction of four general plant projects. The "GPP" projects include the upgrade of Feynman to support needed computational engines, the extension of the New Muon Laboratory to allow the full tests of three cryomodules, the development of the space necessary for the handling of neutrino beam radioactive components in MI-8, and the extension of our industrial building IB-3. By moving rapidly and responsibly to put these funds to work, we will maximize their impact on the economic recovery of our region, including creating jobs largely outside the laboratory. These funds will not only create jobs immediately but will also increase Fermilab's capabilities and efficiency in carrying out our future scientific programs. At the same time we will increase the nation's industrial capabilities to build future accelerator projects.

Our first priority now is to do our part to support economic recovery by spending these funds wisely, productively and rapidly, as contemplated by the legislation. Doing so will demand much of many of us, beyond our planned activities. I ask for your full cooperation when you get requests to pitch in to help with project specifications, quality control and acceptance testing on all aspects of this new body of work. This is an exciting time for science and for Fermilab.
