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…
