Description
The Belle II experiment at the SuperKEKB energy-asymmetric e$^+$e$^-$ collider has completed a series of substantial upgrades and started collecting data since Mar.2019. The designed peak luminosity is 8×10$^{35}$ cm$^{−2}$s$^{−1}$ and the experiment is expected to accumulate a data set of 50ab$^{-1}$ by 2027, to explore new physics beyond the Standard Model at the intensity frontier. The pixel detector (PXD) of Belle II plays a key role in the vertex determination. It has been developed using the DEpleted P-channel Field Effect Transistor (DEPFET) technology, which combines low power consumption in the active pixel area and low intrinsic noise with a very small material budget. In this talk, commissioning and performance of PXD measured with first collision data will be presented.
