Belle experiment introduction
Belle experiment is one of the two largest B-meson factories in the world. It is an international cooperation experiment plan, using the Japanese high-energy accelerator research institute's KEKB accelerator to study CP symmetry destruction. The name Belle originated from the Bell experiment because the study of this experiment required the production of a large number of B mesons, and the source of the production was generated by the collision of electrons and positrons (electron mirror antiparticles, el).
