Description
I will discuss a class of universal dynamics that arise from the worldline effective action of a free massive scalar in AdS_{d+1}. Given a "heavying" sequence of CFT four-point functions of identical operators with increasing scaling dimension, I will provide necessary and sufficient conditions for their limits to be described universally in various Lorentzian kinematic regimes. These results extend the classic theorems of Hartman-Keller-Stoica and Dey-Pal-Qiao to the setting of CFT correlators in d>2, and provide new tests of bulk locality in the heavy regime.
