Belle is a particle physics experiment designed to study the B meson, a particle containing the so-called b- or beauty quark, whose many different decay modes by the Weak Interaction provide measurements and insights on the nature of matter-antimatter asymmetry in the universe. The apparatus consists of the KEKB collider, which accelerates electrons and positrons to high energies and causes them to collide nearly head-on, and the Belle detector, which surrounds the collision point and detects the explosions of particles resulting from electron-positron annihilations.
The Belle detector, contained in a cubical volume more than 7 meters on a side and consisting of many subsystems, is operated by the Belle collaboration, approximately 400 physicists from more than 50 institutes in 14 nations. The experiment turned on in 1999 and has been spectacularly successful, with the number of publications in majors journals exceeding 300 in 2010. The University of Cincinnati group consists of two faculty, two postdoctoral fellows, and 3-5 graduate students and has had major involvement in several dozen of these publications.
