Abstract
The Belle II experiment at KEK in Japan is under final stage of construction to probe New Physics beyond the Standard Model by measuring CP violation phenomena and rare decays of beauty, charm quark and tau lepton. The experiment is being performed at the SuperKEKB e+e− collider with 80 × 1034 cm−2s−1 as an ultimate instantaneous luminosity. As a severe beam background environment is highly anticipated in e+e− collision, a simulation study of the Belle II calorimeter trigger system is indispensable to develop an appropriate trigger algorithm for high trigger efficiency of physics events and an online luminosity. We report preliminary results on various trigger logics and efficiencies of physics and Bhabha events using the Belle II Geant4-based analysis framework called Basf2.
