Physicists recreating conditions of early universe present new data at Quark Matter 2012
August 2, 2012
EVENT: Physicists from the Relativistic Heavy Ion Collider (RHIC), the only operating collider in the U.S., located at the U.S. Department of Energy’s Brookhaven National Laboratory, and the Large Hadron Collider (LHC), located at the European Organization for Nuclear Research (CERN), will present the latest results from their explorations of the primordial quark-gluon plasma that permeated the early universe at the Quark Matter 2012 conference in Washington, D.C. WHEN: Sunday, August 12 – Saturday, August 18, 2012 PRESS BRIEFING: Monday, August 13, 2012, 1:15 p.m.Overview of key findings from RHIC and LHC heavy-ion experiments, with an opportunity for Q&A with program and experiment scientists and nuclear physics theory experts. Congressional A WHERE:Omni Shoreham Hotel, 2500 Calvert St. NW, Washington, D.C. DETAILS: RHIC, a 2.4-mile-circumference particle accelerator that collides a range of heavy ions moving at nearly the speed of light, was the first machine to demonstrate the formation of quark-gluon plasma (QGP) — a nearly perfect liquid of strongly interacting quarks and gluons that filled the early universe before condensing to form protons, atoms, stars, planets, and everything else that makes up the visible universe today. The unexpected properties of this early-universe QGP have largely been confirmed by heavy-ion experiments at the LHC.* But many mysteries remain about the nature of the quark-gluon interactions that hold together our visible world and how they evolved from this primordial soup. The latest findings from RHIC and the LHC will enlighten our understanding and set the stage for future explorations. Presentations from RHIC and LHC experiments will include: •New details about the transition from ordinary matter to QGP •Characteristics of ions before they collide, and effects on collision dynamics •First results from new kinds of ion collisions, including football-shaped uranium ions and non-identical copper on gold •Effects of the QGP on fast quarks and gluons (jet quenching) •Suppression of heavy quark states by the QGP HIGHLIGHTS: The following talks and events may be of special interest to reporters.

Regency Saturday, Aug. 18 8:30 a.m. Talks on the future of RHIC and heavy-ion experiments at the LHC. Regency 2/3 PRESS REGISTRATION: Reporters interested in attending any part of Quark Matter 2012 must register online. For reporters unable to attend in person, we will be webcasting the Monday morning talks and press briefing. To register for either or both webcasts, go to: http://www.aipwebcasting.com/reg-aug-2012.php. Reporters registered for the press briefing webcast will be able to email questions. For more information, contact Karen McNulty Walsh, Brookhaven Lab Media & Communications Office, 631 344-8350, [email protected] For additional background on quark matter physics, see The Exploration of Hot Nuclear Matter, a review article just published in Science, this press release, and a short video about research at RHIC. *Heavy-ion physics at the LHC is a separate research program from the recently publicized search for the Higgs particle. Research at RHIC is funded primarily by the DOE Office of Science, and also by these agencies and organizations. DOE’s Office of Science is the single largest supporter of basic research in the physical sciences in the United States, and is working to address some of the most pressing challenges of our time.
