Cosmological Correlators from Generating Potentials and Projective Geometry
Aswini Bala, Sachin Jain, Deep Mazumdar
We introduce novel scalar generating potentials to compute three and four point cosmological correlators in orthogonal Grassmannian space. These correlators are obtained by applyin…
Exact Color Kinematics Duality in the Cosmological Correlators
Aswini Bala, Sachin Jain, Vibhor Singh
In this paper, we study color kinematics duality and related double-copy and BCJ structures in the cosmological Grassmannian framework. The simplicity of these correlators in this…
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 deformation that leaves all the Grassmannian constraints int…
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…
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…
