|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 integrated luminosity of about 50 ab?1 by 2025 for precise measurements of CP violation and searches for new physics, such as flavor-changing neutral currents, probing charged Higgs, new sources of CP violation, lepton-flavour violating decays, and searches for a dark photon. 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), in such a high rate and background environment, a detailed systematic performance study is essential using the offline reconstruction software. In this work, the performance of the Belle II SVD is validated using commissioning data for each double-sided silicon strip sensor. These studies help us to optimize the operation parameters of the SVD. � Copyright owned by the author(s) under the terms of the Creative Commons.|
