The European Strategy Group (ESG) process has nearly completed. The next major decadal strategy effort is the US Snowmass process, which will be followed by P5 panel recommendations, which in turn will guide funding and resource decisions.
The first milestone for the US Snowmass process is the submission of short 2-page LOI's by Aug 31st, 2020 while longer "white-paper" documents are due before the end of summer next year (2021). These white-papers may update or go beyond the content of the Belle II Physics Book https://arxiv.org/abs/1808.10567 and may also discuss technical aspects of SuperKEKB accelerator and Belle II detector upgrades.
Detailed scientific discussions will take place during the next year and a large close-out meeting is planned in Seattle, WA in the summer of 2021. Participation of all international Belle II colleagues and especially junior colleagues is strongly encouraged in this high energy physics community process. Contributions from theoretical colleagues are also welcomed. Belle II colleagues are encouraged to join the Snowmass topical groups.
