(PhysOrg.com) -- Quarks, the most fundamental constituents of matters, are classified into six species grouped into three generations as predicted by Professors Kobayashi and Maskawa. The purpose of the B factory experiment is to elucidate the fundamental laws of elementary particles by producing B mesons that contain the second heaviest quark (bottom). An international team of researchers at the High Energy Accelerator Research organization (KEK) in Tsukuba, Japan, the "Belle collaboration", has achieved many successes, including the discovery of CP violation in B meson decays and proof of the Kobayashi-Maskawa theory, the discoveries of new decay processes in B decays and D-meson mixing as well as the observation of new resonances.
