Scattering angle at 3PM in scalar-tensor theories using the PM-EFT formalism
Laura Bernard, Tamanna Jain, Stavros Mougiakakos
In this work, we derive the conservative dynamics of non-spinning binaries in the massless scalar-tensor theories using the post-Minkowskian Effective Field Theory (EFT) approach.…

Radiation reaction force for scalar-tensor theories in effective-one-body formalism
Tamanna Jain, Piero Rettegno
Whilst most of the binary configurations in modified theories of gravity are studied under quasi-circular orbit limit, eccentricity effects could play a significant role in future…

Angular Momentum Flux in Scalar-Tensor Theories up to 1.5 post-Newtonian Order
Tamanna Jain, Piero Rettegno
We compute the angular momentum flux from a non-circular nonspinning binary system of compact objects in massless scalar-tensor theories up to one and a half post-Newtonian (1.5PN)…
