Abstract

Violation of matter-antimatter symmetry, the so called CP violation, was observed only as a small effect in the decays of the neutral K meson in 1964. In order to study the long standing puzzle about the origin of the CP violation, the KEK B-factory has been constructed at High Energy Accelerator Research Organization (KEK) in Japan. Using the KEK B-factory and the BELLE detector, an experimental study of the production and decay of the B meson will be carried out to search for the CP violation. Using the BELLE Fast Simulator (FSIM), we made a Monte Carlo simulation study to estimate an integrated luminosity required to observe the signal and CP violation in the charmless hadronic decays of the B mesons. The sensitivity of the BELLE experiment to the measurement of the direct CP violation and branching ratio has been estimated.
