Observation of large CP violation in the neutral B meson system
The measurements of complex parameters (CP) violation using improved reconstruction algorithms in neutral meson system was presented. The data samples were collected with the Belle detector at KEKB symmetric-energy collider. The CP violation in the system was determined from the symmeterrical distribution of the time interval between the two B meson decay points.
