"NUMB3RS" (D)Zeros
in on Fermilab

Every week Larry Fleinhardt helps stop bomb-toting terrorists or serial criminals.

He teaches at a top-notch university.

And although quirky, he won the heart of a beautiful woman.

What could top that? Working with DZero at Fermilab to solve the mysteries of the universe and find the Theory of Everything.

Fleinhardt, played by actor Peter MacNichols, is a sidekick character on the crime drama "NUMB3RS." He accepted an invitation to join DZero during the Jan. 18 episode, calling DZero's research "the work of a lifetime."

The show's writers were drawn to DZero's apt numerical name and its quest to find the Higgs boson. The characters use math to solve crimes and increasingly reference math-based particle physics.

Like real-life physicists, Fleinhardt hit a roadblock trying to create an 11-dimensional supergravity theory, said co-writer Nick Falacci.

The search for an answer takes Fleinhardt to his particle physics roots and a cutting-edge study of extra-dimensional gravitons and the Higgs boson, Falacci added. DZero and its sister detector collaboration, CDF, are leaders of that search at the energy frontier.

DZero members love the idea of inclusion of the show and have created an office for the make-believe physicist in the assembly building.

"I expect it will make more people aware of the work that we do and (if the plot develops) how we actually learn about particle physics," said DZero spokesman Darien Wood. "The characters on the show speak with great excitement and reverence about the search for the Higgs boson at DZero, and I think it captures some of the passion that we real particle physicists have for our work."

The show's creators declined to say how involved the story line will become or if Fermilab will end up on camera.

"Larry's impending involvement with the DZero team will allow 'NUMB3RS' viewers a chance to follow Professor Fleinhardt on his investigative journey into the very strange and fascinating world of fundamental particles," Falacci said.

Record luminosity, pbar stacking records reached

This figure shows the weekly antiproton production. Fermilab set a record last week for most antiprotons collected in a single week.

Yesterday's Tevatron store #5934 had the highest peak luminosity since the end of the 2007 shutdown and the second best initial luminosity in history, at 2.86E32. The best was 2.92E32 on Feb. 25, 2007. Also, last week, the Antiproton Source set a new Pbar weekly record for most antiprotons collected in a single week. Congratulations to all!

U of C asks Congress to aid research

From Chicago Maroon,
Feb. 26, 2008

President Zimmer joined a coalition of university and research industry leaders on Capitol Hill earlier this month to lobby members of Congress and the Bush administration for more funding for scientific research. The officials mobilized in response to a budget cut earlier this year that slashed millions of dollars for science research in this year's final federal budget proposal.

Bob Rosenberg, associate vice president for public affairs and communications at the University, said that the lobbyists are concerned that "the direction of funding for research in this country is flat and trending downward."

The coalition said that they hoped to make a dramatic statement about the importance of funding scientific research through a strong show of numbers. Zimmer was joined by the presidents of Duke University, the University of Maryland, the University of Minnesota, Pennsylvania State University, the University of Alabama, and the University of New Mexico. Industry leaders such as Norman Augustine, retired CEO and chairman of Lockheed Martin Corp.; and Christopher Hansen, president and CEO of American Electronics Association, also participated.

Minooka HS plans science celebration

From Herald News,
Feb. 26, 2008

MINOOKA -- Science teachers, industry leaders, and organizers of the Illinois Science Teachers Association met at Minooka High School this week to discuss ways to celebrate next year's anniversary of the formation of the National Academy of Science and the birthdays of Charles Darwin and Abraham Lincoln.

Donna Engel, a Minooka chemistry teacher and vice president of the association, said the organization of the state's science teachers will begin a year-long initiative in 2009 to raise awareness of science in students, teachers, the community, and the business world.

Local industry leaders from ExxonMobil, Fermi National Accelerator Laboratory, and Lyondell/Basell also attended and gave input on how they were willing to help with the year of celebration.

.....Susan Dahl of Fermilab said her research industry is reaching out to teachers and students right now, and has many resources available for both.

"This is part of our heritage," she said of Fermilab. "We want to make that connection between those who are doing science and those who are teaching it."...

New mixing in the
standard recipe?

This figure demonstrates DZero's measurement of ΔΓs and Φs in the Bs meson system along with the regions compatible with the measurement at 68.3 percent (dashed black line) and 90 percent (solid black line) confidence level. The Standard Model prediction shown as a solid red line.

When particle physicists predict experiment outcomes, they follow a recipe known as the Standard Model: add quarks and leptons to give the batter some substance, pour in electroweak and strong interactions to bind the ingredients together, and then mix just right. From neutrinos to quarks, different particle systems need different mixing. Too much or too little mixing will not bake up to reproduce our universe. Because of the success of the venerable SM recipe, DZero physicists were surprised to find something strange when studying mixing in the Bs meson system.

The neutral Bs meson, made of bottom and strange quarks, can be found in nature in two distinct configurations with different masses and lifetimes. These configurations are understood to be composed of a mixture of states that conserve charge-parity (CP). The SM recipe suggests that this mixing should result in a very small violation of CP conservation. By observing decays of Bs mesons, physicists can determine how much CP mixing really occurs in the Bs system, much like tasting a souffle to determine a baker's secret ingredient. DZero physicists analyzed Bs meson decays to J/ Ψ and Φ mesons (consisting of charm+anti-charm and strange+anti-strange quarks, respectively). When these secondary mesons then decay to two muons and two charged kaons, the DZero researchers were able to get a picture of what happened. By carefully identifying the unique matter and anti-matter versions of the Bs meson, they were able to measure how the CP states of the system were mixed.

In 2.8 inverse femtobarns of data, DZero scientists measured the lifetime difference between the mass eigenstates to be ΔΓs = 0.19+/-0.08 ps-1 and found a CP-violating mixing phase of Φs = -0.57+/-0.31. Though compatible with the SM prediction, such an outcome is statistically expected in only one out of 20 measurements with comparable precision. More data are needed to determine if this result is a fluctuation or a sign of new physics. It's clear that DZero will keep the Bs meson prominent on its physics menu, eager to see if this taste test truly indicates a new recipe for Bs mixing.

A team of researchers from the DZero collaboration made primary contributions to this analysis.

The DZero On-line/Controls team provides reliable support for the experiment's on line computing resources and for the control and monitoring of thousands of parameters of the DZero detector in real time. Their hard work is critical for recording the high-quality data used in all DZero physics analyses.
