Abstract

The Belle II experiment at the SuperKEKB collider of KEK (Japan) will accumulate 50 ab⁻¹ of e⁺e^- collision data at an unprecedented instantaneous luminosity of 8⋅ 10³⁵ cm⁻²s⁻¹, about 40 times larger than its predecessor. The Belle II vertex detector plays a crucial role in the rich Belle II physics program, especially for time-dependent measurements. It consists of two layers of DEPFET-based pixels and four layers of double sided silicon strip sensors (SVD detector). We report here results of the standalone commissioning of the SVD and highlights from the first cosmic runs acquired in Belle II. We also report on reconstruction performances of a reduced-scale version of the SVD operated during the accelerator commissioning in 2018.
