5-Dimensional Gravitational Raman Scattering: Scalar Wave Perturbations in Schwarzschild-Tangherlini Spacetime
Samim Akhtar, Yilber Fabian Bautista, Cristoforo Iossa +1
In this Letter, we study scalar wave perturbations of arbitrary frequency to the 5D Schwarzschild-Tangherlini black hole (STBH) within general relativity. For the first time, we de…

Large deflection scattering, soft radiation and KMOC formalism
Samim Akhtar, Alok Laddha, Arkajyoti Manna +1
KMOC (Kosower, Maybee, and O'Connell) formalism is an approach to analyze classical scattering in gauge theories and gravity using a class of ``inclusive'' observables which can be…

On the classical limit of the (sub)-leading soft graviton theorems in without deflection
Samim Akhtar
Tree-level gravitational amplitudes satisfy an infinite hierarchy of soft factorization theorems. The existence of these theorems has been recently linked with the existence of an…
