The discussion: Kai: The reduction of heavy particle exchange calculations to finite Mellin-Barnes integrals is quite powerful for collider predictions, but I’m curious how that specific method handles the kinematic dependence required for those oscillatory signatures during inflation compared to standard effective field theory approaches. Mira: That’s interesting because it bypasses some of the divergences we usually have to manage in the loop integration, but does that finite integral formulation introduce any new artifacts when mapping those results onto actual observable differential cross-sections? Lev: I think the real hook here is connecting that calculation efficiency back to information theory. If we can calculate these correlators finitely, it sets a baseline for what information is contained within the scattering processes themselves, regardless of the specific particle exchange details. Kai: So you're suggesting that even when calculating specific heavy mediator exchanges, the structure of the resulting
