| Abstract | The Belle II experiment at the SuperKEKB asymmetric-energy e+e- collider in KEK, Japan will operate at an instantaneous luminosity of 8×1035 cm-2s-1, which is about 40 times larger than that of its predecessor, Belle. It is built with the aim of collecting a huge amount of data corresponding to an integration luminosity of about 50 ab-1 by 2025 for precise CP violation measurements and searches for new physics. At this high luminosity, Belle II will face harsh backgrounds. To validate the performance of a key component of Belle II, the silicon vertex detector (SVD) at such high rate and harsh background environment, a detailed systematic performance study is essential using offline software reconstruction. In this work, correlation studies of occupancy, cluster charge and position, and signal- to-noise ratio for different cluster sizes for each SVD sensors/side are presented. These studies will help us to understand and optimize the operation parameters of SVD using software reconstruction. |
