Belle II/SuperKEKB@Snowmass 2021
Details about the 2021 Snowmass Process can be found on the official page: https://snowmass21.org/
The European Strategy Group (ESG) process has completed. The results are available at these URLs: https://cds.cern.ch/record/2721370 and https://cds.cern.ch/record/2720131?ln=en The next major decadal high energy physics 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 was the submission of short 2-page LOI's on Aug 31st, 2020. Longer "White-Paper" documents were submitted by March 15th, 2022. These White-Papers update the content of the Belle II Physics Book https://arxiv.org/abs/1808.10567 and discuss technical aspects of Belle II detector upgrades as well as a polarization upgrade and other SuperKEKB future plans.
The Belle II/SuperKEKB Snowmass White Papers were reviewed at the Rare and Precision Frontier meeting in Cincinnati, Ohio, May 16-19, 2022 https://indico.fnal.gov/event/51844/timetable/#all.detailed. The Snowmass closeout meeting will be held in Seattle, Washington, July 17-26, 2022, https://indico.fnal.gov/event/22303/ and will include a summary of Belle II/SuperKEKB plans and physics opportunities for the future.
