Just what your iPod needs: a Fermilab rap video

Steven Rush, also known as funky49, a science rapper from Tampa, Florida, raps about Fermilab.

Rock stars of physics, particle business
smash matter, anti-matter and witness quarks, bottom to top
they don't stop
"Where the Higgs at?" Yo that's their mark!
Go! Go! Go!

Is this another music video explaining how the Large Hadron Collider at CERN operates? Nope, this time the beats bump and rhymes resonate to pay tribute to the original big-time atom smasher: the Tevatron.

Wired magazine's Nerdcore Hip Hop All-Star funky49 releases today the first music video about Fermilab and its star particle accelerator. Rather than just focusing on how the mammoth machine works, science communicator funky49 looks at how the Tevatron fits into the "big picture": politics, national prominence and your pocketbook.

Although the Tevatron got dethroned this year as the world's highest-energy particle accelerator, a title it held for more than two decades, it remains the world's highest-energy proton-antiproton collider. The Tevatron also remains firmly in the race against the LHC in Switzerland to find the Higgs boson, a.k.a. the God Particle.

DOE Press Release

Department of Energy releases open government plan

From April 7, 2010

The U.S. Department of Energy today released its Open Government Plan highlighting DOE initiatives to maintain and increase transparency, increase participation between the Department, its program offices, sites and the American public, and increase collaborative efforts between the Department and its stakeholders.

"We are strongly committed to making government work better for the American people," said Secretary Chu. "Through transparency and openness, we will provide better service to the public, give citizens a better understanding of how the Department works, and create new opportunities for people to engage the Department on issues that matter to them."

The plan highlights flagship initiatives spearheaded by DOE including the launch of Open Energy Information (OpenEI.org), a new open-source web platform that opens DOE resources and data to the public. The free, editable, and evolving wiki-platform will help to deploy clean energy technologies across the country and the world. OpenEI.org also will provide technical resources, including U.S. lab tools, which can be used by developing countries as they move toward clean energy deployment.

Additional initiatives include ScienceEducation.gov, an interagency website and networking tool for the Science Technology Education and Math (STEM) education community; and the Energy Information Administration's (EIA) Education and Literacy Initiative. The EIA Initiative is comprised of Energy Explained, an encyclopedia of energy issues; Energy in Brief, an article series; and Energy Kids, an interactive website for students and teachers.

Fermilab in race to find God particle

From Medill Reports, April 7, 2010

The atom smasher at the Fermi National Accelerator Laboratory west of Chicago may still lead the charge in finding an elusive particle-the Higgs boson or "God particle"-that could help explain the makeup of all matter in the universe.

The Fermilab is now in a race with the new kid on the block-the far more powerful "Big Bang" collider in Switzerland. That collider, known as the Large Hadron Collider (LHC), has the edge on energies that can give scientists a time machine back to the first milliseconds after the Big Bang. Particles collide at high enough energies to mimic conditions that might have existed then. But the Higgs could be found at either lab.

According to physicists, the theoretical Higgs boson neatly ties together the Standard Model of matter that accounts for the particles and subsequent interactions that create mass. A coffee cup, for example, is made up of many atoms arranged in a certain way. Yet scientists so far have been unable to explain why those atoms stay together at the most fundamental level.

Do SUSY and Higgs travel together?

The two-jet mass spectrum in the three b-quark event sample from in 2.5 inverse femtobarns of CDF data. bbB, bBb, etc. are nicknames for Standard Model processes with three b-quarks that comprise most of the sample. The small SUSY-Higgs-like excess is shown in red.

Could the Tevatron reveal supersymmetry (SUSY) and the elusive Higgs boson at the same time? A new result from CDF examines this possibility by searching for a supersymmetric Higgs boson produced in events with an extra bottom quark, or b-quark.

The Standard Model of particle physics predicts a very small rate for this process, but in SUSY models the rate could be high enough to observe at the Tevatron. Since these SUSY Higgs bosons decay into a pair of b quarks, the final signature is three simultaneous b-quarks, showing up as three high-energy particle b-jets that contain b-hadrons.

Because the b-hadrons travel a measurable distance from the collision point before decaying into other particles, scientists can identify the b-jets using information from CDF detector tracking systems. Events from non-Higgs processes with three b-jets are relatively rare but would still outnumber the SUSY Higgs events, so the search looks for an enhancement in the mass value of the two most energetic b-jets. The non-Higgs processes occur at all masses, but events containing a SUSY Higgs would pile up in a region around the mass of the Higgs boson.

The two-jet mass spectrum of three b-events is shown in the figure, along with a prediction of the background processes. A small excess of events near a mass of 140-150 GeV/c2 is consistent with the hypothetical SUSY Higgs boson contribution, shown in red. A statistical calculation shows a 6 percent chance that this is just the result of random measurement fluctuations, so the jury is still out. The only way to know if this excess is a signal from a Higgs boson is to examine more data. If SUSY and the Higgs boson travel together, then increasing the dataset used in this analysis may be all that scientists need to trap them in the same net.
