Unitarity, Recursion and Soft Limits in (EA)dS through Dressing

Arhum Ansari, Deep Mazumdar, Brijesh Thakkar

Using the recently developed framework in which cosmological correlators in (E)AdS are represented as flat-space amplitudes dressed by auxiliary propagators, we show that several s…

Cosmological Cutting Rules from Flat-Space Unitarity via Dressing

Arhum Ansari, Sachin Jain, Deep Mazumdar

Using cosmological dressing rules, we uplift flat-space unitarity cuts to discontinuity relations for dS/EAdS observables. In this representation, Cutkosky delta functions map dire…
