The eikonal operator at arbitrary velocities I: the soft-radiation limit
Paolo Di Vecchia, Carlo Heissenberg, Rodolfo Russo +1
Observables related to the real part of the gravitational eikonal, such as the deflection angle and time delay, have been found so far to have a smooth post-Minkowskian (PM) expans…
Second-order Post-Minkowskian scattering in arbitrary dimensions
Andrea Cristofoli, Poul H. Damgaard, Paolo Di Vecchia +1
We extract the long-range gravitational potential between two scalar particles with arbitrary masses from the two-to-two elastic scattering amplitude at 2nd Post-Minkowskian order…
The Holographic QCD Axion
Francesco Bigazzi, Alessio Caddeo, Aldo L. Cotrone +2
A holographic model of QCD axion is presented. It describes a composite axion in the KSVZ class. Having a gravity dual, based on the Witten-Sakai-Sugimoto model, it is calculable i…
Revisiting the 2PM eikonal and the dynamics of binary black holes
Arnau Koemans Collado, Paolo Di Vecchia, Rodolfo Russo
In this paper we study the two-body gravitational scattering of massive scalars with different masses in general spacetime dimensions. We focus on the Regge limit (eikonal regime)…
The Subleading Eikonal in Supergravity Theories
Arnau Koemans Collado, Paolo Di Vecchia, Rodolfo Russo +1
In this paper we study the subleading contributions to eikonal scattering in (super)gravity theories with particular emphasis on the role of both elastic and inelastic scattering p…
