Abstract

The Belle II experiment at the SuperKEKB accelerator in Tsukuba, Japan, is a second-generation B factory experiment. Belle II will benefit from an approximate factor of 40 increase in the instantaneous luminosity with respect to the previous Belle / KEKB experiment, due to significantly reduced beam interaction profile, and higher beam current. In this talk, I will present some results and prospects for dark sector physics measurements on early data, as well as some select important physics measurements over the lifetime of the Belle II experiment. I will focus on areas where there is complementarity with LHCb. In particular the rare B decay modes that can help to shed light on recent anomalies observed by LHCb.
