Improvement of Kaon identification at the Belle experiment

초록

Kaon identification(KID) performance is significant to extract event signal and suppress combinatorial background for all physics analyses at the Belle experiment. Belle KID has been performed by three main subdetectors, Aeorogel Cherenkov Counter(ACC), Central Drift Chamber(CDC),and Time Of Flight(TOF). We report the improved KID performance using new PDF into ACC part.
