The BELLE experiment took the data
from Nov. 12 to Dec. 16 after the summer
shutdown in the last year. During the operation
in that period, the KEKB accelerator steadily
improved the luminosity. The integrated luminosity
was 280  since the beginning of the BELLE in Jun.
1999. The maximum luminosity in the fall
period was about 18 per day. The data analysis has been carried out and showed an accumulation of a large number of the B meson decay events. The data taking will be resumed on Jan. 14, 2000. The figure shows a typical event of the B meson decay process  |
