QG group meetng - dS S-matrix status report

This is the weekly QG group meeting.
Speaker: Yasha Neiman, Ph.D., IDF First Sergeant (reserve).
Title: "dS S-matrix status report"

I will discuss our last paper on the free S-matrix in de Sitter space. I will then do a consciousness dump vis. the two possible forays into the land of interactions: ordinary "lower-spin" theories, i.e. Yang-Mills/GR, and higher-spin gravity.
