Carnegie Mellon University Physicist Curtis Meyer Elected Fellow of the American Physical Society
PITTSBURGH—Carnegie Mellon University physicist Curtis Meyer has been elected a fellow of the American Physical Society (APS) for his contributions to and his leadership in the experimental study of the light quark spectrum and the role of gluonic excitations. Election as a fellow is limited to one half of one percent of the APS membership each year.
Meyer, a professor of physics at the Mellon College of Science (MCS), specializes in medium energy physics. In his early research at CERN (the European particle physics laboratory in Geneva), he played a key role in discovering several hybrid mesons. These subatomic entities combine forcecontaining particles called gluons with other particles called quarks.
Meyer is currently designing part of an instrument for GlueX, a large-scale Carnegie Mellon-led project in nuclear physics that in fall 2004 received a green light to move forward from the Department of Energy. GlueX is part of a major upgrade of the Thomas Jefferson National Accelerator Facility in Newport News, Va.
The GlueX experiment will spearhead new physics that allows scientists to address one of the greatest mysteries of modern physics—the mechanism that "confines" quarks inside protons and neutrons. In recent years, supercomputer models have indicated that gluons create fields called "fluxtubes," and these flux-tubes may be responsible for confining quarks inside protons. By exciting these flux-tubes with high-energy beams of photons, the GlueX researchers hope to generate new families of particles that will lead to a better understanding of how quarks are bound to one another.
Meyer is an author or co-author of more than 130 refereed articles. He has organized many conferences and workshops, in addition to serving on several national advisory committees. A founding member of the APS Topical Group on Hadronic Physics, Meyer served as the chair of the program committee for several years. He also was a board member of the Jefferson Lab User's group and has served on advisory and editorial boards related to the Jefferson Lab 12 GeV upgrade.
