'''KEKB''' is the name of a particle accelerator used in the [[Belle experiment]] to study [[CP violation]]. It is called a [[B-factory]] for its copious production of B-mesons which provide a golden mode to study and measure the [[CP violation]] due to its property of decaying into other lighter mesons. KEKB is basically an [[symmetry|asymmetric]] [[electron]]–[[positron]] [[collider]], with [[electron]]s having the energy of 8 [[GeV]] and [[positron]]s having the energy of 3.5 [[GeV]], giving 10.58 GeV centre-of-mass energy, which is equal to the mass of the '''[[Upsilon meson|Upsilon(4S)]]''' meson.


There are basically two rings for [[accelerating]] [[electron]]s and [[positron]]s. The ring for electrons, having energy of 8 GeV, is called the high-energy ring (HER), while the ring for positrons, having energy of 3.5 GeV, is called low-energy ring (LER). The HER and LER are constructed side-by-side in the tunnel, which has been excavated already in the past for the former TRISTAN accelerator. (TRISTAN was the first site to confirm [[vacuum polarization]] around an electron.)<ref>{{cite journal
