About 70 attendees are expected for the collaboration‚Äôs 30th annual workshop, which will be held from Friday, June 7, through Tuesday, June 11.
Over the years, the collaboration has involved 82 institutions from 18 countries and hundreds of scientists and engineers from across the globe. The experiment was conducted at Fermilab‚Äôs Tevatron accelerator, which shut down Sept. 29, 2011. Results are still being analyzed, however.
The Tevatron had been the world‚Äôs largest proton-antiproton collider. It accelerated and stored beams of protons and antiprotons traveling in opposite directions around an underground ring four miles in circumference at almost the speed of light before colliding them at the center of two detectors.
The experimental collaborations were named after the detectors: CDF, for Collider Detector at Fermilab, and DZero, for its location on the accelerator ring. Each contained many detection subsystems that identified the different types of particles emerging from the collisions.
Scientists explored the structure of matter, space and time by analyzing the showers of particles created.
Ultimately, the Tevatron helped physicists discover the elusive top quark particle, find strong hints of the Higgs boson, more fully understand nature‚Äôs forces and observe and measure the properties of the smallest things ever seen, such as quarks and the carriers of the weak nuclear force.
For the past three decades, DZero was the primary focus of NIU‚Äôs High Energy Physics (HEP) group, with eight faculty members, 11 scientists, 44 graduate students and 90 undergrads having worked on the collaboration. NIU physicists David Hedin, Gerald Blazey, Dhiman Chakraborty, Michael Fortner and Michael Eads all are still members of DZero.
‚ÄúDZero has been an extremely productive experiment and has helped to rewrite modern physics textbooks,‚ÄĚ said Blazey, who served as co-spokesman for the collaboration from 2002 to 2006.
Hedin, a lead organizer for the workshop, is one of DZero‚Äôs founding fathers. ‚ÄúThis 30th anniversary workshop is in some sense the collaboration‚Äôs swan song as we move toward completing the last 10 to 20 research papers,‚ÄĚ he said.
