Classical gravitational scattering with a massive scalar mediator
Birgitta Biendarra, Kays Haddad, Jan Plefka
We consider the classical scattering of two gravitating compact objects in the presence of a massive scalar mediator, providing a simple model of exotic phenomena. Through dimensio…
Gravitational wave scattering at : Murua construction and elliptics
Yilber Fabian Bautista, Mathias Driesse, Kays Haddad +1
We compute the amplitude for the scattering of a gravitational wave off of a spinless point particle at fourth order in Newton's constant, using the worldline quantum field theory…
Gravitational Wave Scattering in Spinless WQFT
Yilber Fabian Bautista, Mathias Driesse, Kays Haddad +1
We develop the computational framework for gravitational wave - black hole scattering in worldline quantum field theory (WQFT) without spin. Crucially, we prove on general grounds…
Unitarity and the On-Shell Action of Worldline Quantum Field Theory
Kays Haddad, Gustav Uhre Jakobsen, Gustav Mogull +1
We develop the on-shell action formalism within Worldline Quantum Field Theory (WQFT) to describe scattering of spinning compact bodies in General Relativity in the post-Minkowskia…
Spinning bodies in general relativity from bosonic worldline oscillators
Kays Haddad, Gustav Uhre Jakobsen, Gustav Mogull +1
Worldline quantum field theory (WQFT) has proven itself a powerful tool for classical two-body scattering calculations in general relativity. In this paper we develop a new worldli…
