On Positive Geometries of Quartic Interactions II : Stokes polytopes, Lower Forms on Associahedra and Worldsheet Forms
P B Aneesh, Pinaki Banerjee, Mrunmay Jagadale +3
In [1], two of the present authors along with P. Raman attempted to extend the Amplituhedron program for scalar field theories [2] to quartic scalar interactions. In this paper we…

Accordiohedra as positive geometries for generic scalar field theories
P. B. Aneesh, Mrunmay Jagadale, Nikhil Kalyanapuram
We build upon the prior works of [1-3] to study tree-level planar amplitudes for a massless scalar field theory with polynomial interactions. Focusing on a specific example, where…

Conserved charges in asymptotically de Sitter spacetimes
P B Aneesh, Sk Jahanur Hoque, Amitabh Virmani
We present a covariant phase space construction of hamiltonian generators of asymptotic symmetries with `Dirichlet' boundary conditions in de Sitter spacetime, extending a previous…
