A Cosmological BCFW Bridge and Its Canonical Geometry

Aswini Bala, Sachin Jain, Vibhor Singh

We build a BCFW-like recursion for cosmological correlators using the orthogonal Grassmannian. The key step is a bridge transformation that leaves all the Grassmannian constraints…

Super-Grassmannians for to SCFT: From AdS Correlators to SYM scattering Amplitudes

Aswini Bala, Sachin Jain, Dhruva K. S. +1

We construct a Super-Grassmannian for point functions in to SCFT. The constraints imposed by super-conformal invariance and symmetry are completely…

The Super-Grassmannian for CFT and a Foray on AdS and Cosmological Correlators

Aswini Bala, Sachin Jain, Dhruva K. S. +1

We construct a Super-Grassmannian integral representation for point functions in SCFT. In this formalism, conformal invariance, supersymmetry, and special s…

AdS Boundary Wightman functions in Twistor Space: Factorization, Conformal blocks and a Double Copy

Arhum Ansari, Sachin Jain, Dhruva K. S

We study real-time holographic four point Wightman functions involving scalars, photons, gluons and gravitons in the Poincare patch of AdS. We show that when the momenta of the…

Hidden sectors of Chern-Simons Matter theories and Exact Holography

Sachin Jain, Dhruva K. S, Evgeny Skvortsov

Chiral higher-spin gravity is a higher-spin extension of both self-dual Yang-Mills and self-dual gravity and is a unique local higher-spin gravity in four dimensions. Its existence…

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…
