Celestial insights into the S-matrix bootstrap
Sudip Ghosh, Prashanth Raman, Aninda Sinha
We consider 2-2 scattering in four spacetime dimensions in Celestial variables. Using the crossing symmetric dispersion relation (CSDR), we recast the Celestial amplitudes in terms…
Crossing Symmetric Spinning S-matrix Bootstrap: EFT bounds
Subham Dutta Chowdhury, Kausik Ghosh, Parthiv Haldar +2
We develop crossing symmetric dispersion relations for describing 2-2 scattering of identical external particles carrying spin. This enables us to import techniques from Geometric…
QFT, EFT and GFT
Prashanth Raman, Aninda Sinha
We explore the correspondence between geometric function theory (GFT) and quantum field theory (QFT). The crossing symmetric dispersion relation provides the necessary tool to exam…
Stringy canonical forms and binary geometries from associahedra, cyclohedra and generalized permutohedra
Song He, Zhenjie Li, Prashanth Raman +1
Stringy canonical forms are a class of integrals that provide -deformations of the canonical form of any polytopes. For generalized associahedra of finite-type cluster algebra,…
The positive geometry for interactions
Prashanth Raman
Starting with the seminal work of Arkani-Hamed et al arXiv:1711.09102, in arXiv:1811.05904, the "Amplituhedron program" was extended to analyzing (planar) amplitudes in massless $ϕ…
Stokes Polytopes : The positive geometry for interactions
Pinaki Banerjee, Alok Laddha, Prashanth Raman
In a remarkable recent work [arXiv : 1711.09102] by Arkani-Hamed et al, the amplituhedron program was extended to the realm of non-supersymmetric scattering amplitudes. In particul…
Scalar Blocks as Gravitational Wilson Networks
Atanu Bhatta, Prashanth Raman, Nemani V. Suryanarayana
In this paper we continue to develop further our prescription [arXiv:1602.02962] to holographically compute the conformal partial waves of CFT correlation functions using the gravi…
Holographic Conformal Partial Waves as Gravitational Open Wilson Networks
Atanu Bhatta, Prashanth Raman, Nemani V. Suryanarayana
We propose a method to holographically compute the conformal partial waves in any decomposition of correlation functions of primary operators in conformal field theories using open…
