This is an overview of selected papers contributed by the Theory Frontier (TF) to Snowmass 2021. Due to my interest, I’m biased towards theory-related topics 😜.
A list of reports and contributed papers can be found on C210711/Theory with the preprints for TF white papers on arXiv.
The blog 4gravitons has an interesting post a while back, giving the origin of the word Snowmass and how Snowmass 2021 is substantially different from previous years’ meetings.
