eal Ambitwistors & Massive Twistors for CFT
Aswini Bala, Sachin Jain, Deep Mazumdar +1
We develop a real twistor-space formulation of four-dimensional CFT Wightman correlators. We write the conformal generators and little-group constraints in ambitwistor space. The q…
Unitarity, Recursion and Soft Limits in (EA)dS through Dressing
Arhum Ansari, Deep Mazumdar, Brijesh Thakkar
The paper shows that many properties of cosmological correlators in (E)AdS can be derived from flat‑space amplitudes by dressing them with auxiliary propagators, establishing cutti…
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…
Super-Penrose Witten Transforms for SCFT
Deep Mazumdar
The study of three dimensional CFT correlators in twistor space has recently garnered a significant interest. Conformal symmetry acts linearly in the twistor space, which streamlin…
A Supertwistor Formalism for
Aswini Bala, Sachin Jain, Dhruva K. S. +3
We develop a manifest supertwistor space formalism for three dimensional superconformal field theories. This formalism simultaneously makes manifest the supe…
3D Conformal Field Theory in Twistor Space
Aswini Bala, Sachin Jain, Dhruva K. S. +2
The aim of this paper is to study three dimensional Lorentzian conformal field theories in twistor space. We formulate the conformal Ward identities and solve for two and three poi…
