Performance of the Belle II SVD

The Belle II at SuperKEKB will accumulate e$$^{+}$$e$$^{-}$$ collision data at an unprecedented instantaneous luminosity of $$8 \times 10^{35}\,\mathrm{cm}^{-2}\,\mathrm{s}^{-1}$$, about 40 times larger than its predecessor (Belle). Such a dramatic increase in luminosity will result in a harsh background environment in Belle II. In this paper, we present the detailed performance studies of the Belle II silicon vertex detector with test beam data and Phase II data.
