High Energy Theory Seminar

I will review recent developments in the understanding of Lorentzian correlators in generic CFTs. I will then discuss two applications of these developments. The first one involves bounds on the OPE coefficients on the leading Regge trajectory. In theories with gravity duals, it constrains certain higher-derivative corrections to the Einstein theory. The second application is the computation of four-point functions in CFTs with weakly broken higher spin symmetry.
