Theoretical Physics Seminar: Yasha Neiman
This is the 24th biweekly session of the OIST Theoretical Physics Seminar.
In this seminar series, we pretend to have a theoretical physics department, and tell each other informal stories over drinks and snacks.
Speaker: Yasha Neiman (Quantum Gravity).
Title: "Scattering in the causal diamond"
I will talk about my ongoing struggle to think about and calculate scattering amplitudes in causal diamonds in flat spacetime, and in observable patches of de Sitter space. Despite its seemingly low symmetry, this problem is more tractable than could be expected, by virtue of having a square root. Did anyone say supersymmetry? Not me.
