Quasi-Keplerian parametrization for compact binaries on hyperbolic orbits in scalar-tensor theories at second post-Newtonian order
Davide Usseglio, David Trestini, Abhishek Chowdhuri
We obtain the generalized quasi-Keplerian parametrization for compact binaries on quasihyperbolic orbits at second post-Newtonian (2PN) order in a class of massless scalar-tensor t…

Post-Minkowskian self-force in the low-velocity limit: scalar field scattering
Donato Bini, Andrea Geralico, Chris Kavanagh +2
In this paper we present an approach to compute analytical post-Minkowskian corrections to unbound two-body scattering in the self-force formalism. Our method relies on a further l…

A variational framework for higher order perturbations
F. Chiaffredo, L. Fatibene, M. Ferraris +2
A covariant, global, variational framework for perturbations in field theories is presented. Perturbations are obtained as vertical vector fields on the configuration bundle and th…
