Abstract
TheBelle II experiment at SuperKEKB continues to pursue high-precision measurements in Standard Model studies and in searches for physics beyond the Standard Model, with a target dataset of 50 ab−1 and peak luminosities of 6×1035 cm−2s−1. The current Vertex Detector (VXD), composed of the DEpleted P-channel Field Effect Transistor (DEPFET)-based Pixel Detector (PXD) and double-sided strip-based Silicon Vertex Detector (SVD), has achieved excellent tracking and vertexing performance through Run 1 and Run 2. To address future challenges from increased luminosity and background, anewall-pixel VertexDetector (VTX)isunderdevelopment, utilizing radiation-hard DMAPS technology based on the OBELIX sensor. In this contribution, we present the performance of the current VXD system, highlight operational challenges, and present the validation and integration status of the upcoming VTX upgrade.
