On Tuesday, May 11, 2004, the U.S. Environmental Protection Agency and
Chicago Wilderness presented Fermilab with a 2003 Conservation and Native
Landscaping Award at a ceremony in Chicago's Jackson Park. Bharat Mathur,
Acting Regional Administrator for U.S. EPA Region 5, and Elizabeth McCance,
Director of Conservation Programs for Chicago Wilderness, cited Fermilab's
achievement in using native plants in the Main Injector Wetland Mitigation Project.
"These awards recognize outstanding examples where people have used native
plants to bring beauty and diversity to the areas in which we live," McCance
said. "The recipients of today's awards are models for the rest of us. They
have changed their sites into thriving natural communities and made them a
better place to work and live."

Fermilab Arts Series Presents Sam Bush
Tickets Still Available!
The Fermilab Arts Series presents the master musician and bluegrass rebel Sam Bush
on Saturday, May 15 at 8:00 p.m. in Ramsey Auditorium.
Perhaps best known as the founder and driving force behind the legendary New

Sam Bush |
Grass Revival, Bush's ability to make music that exceeds all expectations is
evident by listening to his work over the past year.
Two diverse projects, Bluegrass Mandolin Extravaganza and Short Trip Home, were nominated for Grammy Awards for Best Bluegrass Album and Best Classical Crossover Album, respectively.
The Short Trip Home project led to a performance on the national broadcast
of the Grammy Awards.
He also recently made a guest
appearance with Ringo Starr playing "With A Little Help From My Friends."

From the Oregonian, May 12, 2004
Spirited greeting primes teens for views, advice of scientists
Students at the science fair spring to their feet at the arrival
of eight award-winning researchers
by Richard L. Hill
The spirited teenagers jumped to their feet, clapping and unleashing
a fusillade of camera flashes as they spotted their heroes walking
on stage Tuesday in the Oregon Convention Center.
Rock stars? No, eight award-winning scientists -- including five
Nobel laureates -- who seemed surprised by the spontaneous display
of appreciation from the young crowd of about 500.

DZero: Angling in on QCD

The measured distribution of azimuthal angle between the two most energetic
jets in proton-antiproton collisions.(Click on image for larger version.) |

Quantum Chromodynamics (QCD) is a theory that describes strong interactions among elementary particles. Although it is complete and based on fundamental principles of nature, it is often difficult to apply to specific situations. Nevertheless, comparing approximate calculations from QCD with experiment data offers a way to improve our descriptions of the strong force. For example, when two partons (quark or gluon constituents of protons) smash into one another, they usually emerge back-to-back from the viewpoint of the incoming protons. When additional partons are also produced, QCD predicts how the angle between the two most energetic ones should change.
The signature for outgoing partons corresponds to collimated sprays of particles (remnants of quarks or gluons, referred to as jets) that can be measured through the energy they deposit in the detector. DZero has studied the angle between the two most energetic jets in proton-antiproton collisions, and finds (see accompanying figure) that the emission of extra partons affects the angle between the most energetic jets exactly as predicted from what is referred to as perturbative QCD (labeled NLO in the figure). This kind of information provides a deeper understanding of QCD, better tools for obtaining more reliable calculations, and thereby more sensitivity for gauging any departures from theory that could signal the presence of new physical phenomena.
