000001764 520__ $$aThe Belle II experiment, which recently began collecting e+e- collision data, will extend the successful physics program of BABAR and Belle with a 30-fold increase in integrated luminosity and an improved detector. In particular, the vertex position resolution of Belle II is better than that of its predecessors by about a factor of two. The high resolution and the very small e+e- collision region provide a powerful constraint that can be used in a number of B-physics analyses. This talk will cover studies performed with this method, as well as the performance of the Belle II experiment based on data collected in 2019.
