sBelle Design Study Report (2008)
Adachi, I., Danilov, M., Hara, K., Hara, T., Higuchi, T., Inami, K., ...
In this note, we compile results of various simulation studies for the upgrade of the Belle detector. Based on these studies, we propose a set of optimum or appropriate parameters of the detector.
