Abstract:
The proposal that DSSYK at infinite temperature is dual to JT deSitter space leads
to the question of what the bulk theory is like, its particle spectrum, forces, fields etc. I will answer that question by examining the emergent symmetries of the double scaled limit. The answer: The ‘t Hooft model 2D QCD. The spectrum consists of a Regge-like trajectory of mesons but unlike the usual ‘t Hooft limit the mesons have non-vanishing interaction. If time permits I will discuss the implication for the fine-tuning problem of de Sitter space
