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…
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…
The Conformal Grassmannian: A Symplectic Bi-Grassmannian for Correlators
Aswini Bala, Sachin Jain, Dhruva K. S
We introduce a formalism for conformal field theory in four dimensions: a symplectic bi-Grassmannian representation of CFT Wightman correlators. Working in Klein space with off…
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…
An Ode to the Penrose and Witten transforms in Twistor space for 3D CFT
Aswini Bala, Dhruva K. S
Here we discuss the construction of Sp invariant objects in the twistor space for three dimensional conformal field theories. The Sp invariant proje…
