Soft Constraints on KMOC Formalism
Yilber Fabian Bautista, Alok Laddha
In this note, we investigate the implications of classical soft theorems for the formalism developed by Kosower, Maybee and O'Connell (KMOC) to derive classical observables in gaug…
Causality constraints in Quadratic Gravity
Jose D. Edelstein, Rajes Ghosh, Alok Laddha +1
Classifying consistent effective field theories for the gravitational interaction has recently been the subject of intense research. Demanding the absence of causality violation in…
BMS Algebra, Double Soft Theorems, and All That
Miguel Campiglia, Alok Laddha
The Lie algebra generated by supertranslation and superrotation vector fields at null infinity, known as the extended BMS (eBMS) algebra is expected to be a symmetry algebra of the…
Towards Positive Geometry of Multi Scalar Field Amplitudes : Accordiohedron and Effective Field Theory
Mrunmay Jagadale, Alok Laddha
The geometric structure of S-matrix encapsulated by the "Amplituhedron program" has begun to reveal itself even in non-supersymmetric quantum field theories. Starting with the semi…
