B Physics at KEKB Factory

초록

The Belle experiment performed at the asymmetric electron-positron KEKB collider operating at the Upsilon(4S) resonance has been in operation since 1999. The scientific productivity of the Belle experiment has been very remarkable with wide-ranging pioneering studies of CP violation in the B meson system that demonstrated all CP violating phenomena of the three generation Standard Model as well as studies of rare decay phenomena and high precision measurements in B and D meson and tau lepton decays to serach for beyond Standard Model. In this talk several hot physics results will be presented.
