Reconstructing cosmological correlators via dispersion: from cutting to dressing rules
Shibam Das, Debanjan Karan, Babli Khatun +1
In this work, we investigate how cosmological correlators can be reconstructed by applying the momentum-space dispersion formula to their discontinuities, treating them as function…

A single-cut discontinuity for cosmological correlators from unitarity and analyticity
Shibam Das, Debanjan Karan, Babli Khatun +1
We derive discontinuity relations, also known as cutting rules, and explore the analytic properties of cosmological correlators, fundamental observables of the primordial universe.…
