Abstract

The Belle II experiment at the SuperKEKB collider of KEK (Japan) will accumulate 50 ab1 of e+e collision data at an unprecedented instantaneous luminosity of 8×1035cm2s1, 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 (PXD) and four layers of double sided silicon strip detectors (SVD). The VerteX Detector has been recently completed and installed in Belle II for the physics run started in spring 2019. We report here results on the commissioning of the SVD and its performance measured with the first collision data set.
