EPS recognizes Don Lincoln

Don Lincoln

The European Physical Society High-Energy and Particle Physics Division has awarded its 2013 Outreach Prize to Fermilab physicist Don Lincoln "for communicating in multiple media the excitement of high-energy physics to high-school students and teachers and the public at large."

Lincoln is the first non-European to be awarded the EPS HEPP Outreach Prize.

The annual award is intended to recognize outstanding outreach achievements connected with high-energy physics or particle astrophysics.

Four Chicago-area artists showcase drawings at Fermilab Art Gallery

Steve Carrelli's drawing "Away and Back" is on display in the Fermilab Art Gallery.

Chicago artist Steven Carrelli uses art to explore the relationships between people and the space around them. His still-life drawings seem ordinary at first but reveal different perspectives upon closer inspection.

"The longer you look at it, the stranger the space becomes," Carrelli said.

Carrelli is one of four artists whose pencil-drawn pieces are featured at Fermilab's second-floor art gallery in a show titled "Foundations of Drawing."

Most works on display are in what some may consider the simplest of media: pencil and paper. But the artists' interpretations of various still-life scenes and landscapes can be complex, said coordinator Georgia Schwender.

"I wanted to showcase drawings and the many ways they can be interpreted," Schwender said. "Some have very straightforward meanings, while others have a less literal translation."

Schwender chose to highlight the drawing skills of local and Chicago-based artists in the exhibition.

Among the works shown are highly detailed cityscapes by artist Todd Serrano and decorative drawings by artist Lelde Kalmite that walk the line between fantasy and reality. Ceramics with intricate drawings by artist Laurie Shaman are also featured.

Carrelli, who has been an artist for around 20 years. He has shown work in galleries around the United States and said he is excited to show at Fermilab for the first time.

"I was delighted to find that art has been a part of Fermilab for a very long time," he said. "It's definitely a unique program."

A reception will be held in the gallery on Friday, May 17, from 5 to 7 p.m. and is open to employees and the public. The work will be on display until July 8.

Fermilab narrows search for new director to three finalists

From the Chicago Tribune, May 15, 2013

The search for Fermilab's new director has been narrowed to three finalists, with a decision likely this summer, officials for the national laboratory announced last week.

A 16-member search committee has been working since November to find a replacement for Pier Oddone, who is stepping down July 1, said Katie Yurkewicz, Fermilab's communication director.

IceCube Neutrino Observatory reports first evidence for extraterrestrial sources of high-energy neutrinos

From University of Wisconsin-Madison News, May 15, 2013

A massive telescope in the Antarctic ice reports the detection of 28 extremely high-energy neutrinos that might have their origin in cosmic sources. Two of these reached energies greater than 1 petaelectronvolt (PeV), an energy level thousands of times higher than the highest energy neutrino yet produced in a manmade accelerator.

Frontier Science Result:
CDF and DZero

The power of two top detectors

Complementary experiments enhance the Tevatron physics program by improving searches and measurements.

Two independent experiments, CDF and DZero, recorded the results of the proton-antiproton collisions provided by the Tevatron, and their complementary efforts have proven greater than the sum of their parts. Each collaboration scrutinizes its collected data, searching for signs of new physics while making precise measurements of particle properties in order to improve our understanding of the Standard Model. Comparing and combining the separate results from each collaboration can benefit the field of high-energy physics more than if a single experiment had just collected twice as much data.

The detector is the "lens" a particle physicist uses to investigate the subatomic world. The CDF and DZero detectors are like two different digital cameras, each as large as a four-story apartment building. A significant amount of effort in each collaboration goes into understanding how its particular detector will affect the way scientists see subatomic interactions, and these effects must be carefully accounted for in each physics analysis. Each group of physicists may also perform their physics analyses using different techniques. These differences allow independent verification of any signs of new physics, since it should appear in each experiment regardless of the detector technology or analysis technique.

The sensitivity of a search, or the precision of a measurement, is limited both by statistics, or the amount of data used, and systematics, which includes effects from the detector and the analysis methods used. If the largest uncertainty in a search or measurement originates from a systematic, then simply taking more data with the same detector may not improve the result. Combining results from both experiments not only doubles the amount of data used, which decreases the statistical uncertainty, but it may also reduce the total systematic uncertainty since the effects from each detector are largely independent. Combinations between the Tevatron experiments have helped improve the sensitivity of searches for the Higgs boson, the measurement of the mass of the W boson and more. The latest preliminary combined result from the CDF and DZero collaborations provides the best measurement of the unique production rate for top quark pairs at the Tevatron. These combined results will prove to be part of the legacy of the Tevatron, providing important information that will constrain future models of physics.
