Infrared features of gravitational scattering and radiation in the eikonal approach
Marcello Ciafaloni, Dimitri Colferai, Gabriele Veneziano
Following a semi-classical eikonal approach --- justified at transplanckian energies order by order in the deflection angle --- w…
Radiation enhancement and "temperature" in the collapse regime of gravitational scattering
Dimitri Colferai, Marcello Ciafaloni
We generalize the semiclassical treatment of graviton radiation to gravitational scattering at very large energies and finite scattering angles , so as to ap…
Unitarity restoring graviton radiation in the collapse regime of scattering
Marcello Ciafaloni, Dimitri Colferai
We investigate graviton radiation in gravitational scattering at small impact parameters and extreme energies , a regime in which classical colla…

Unified limiting form of graviton radiation at extreme energies
Marcello Ciafaloni, Dimitri Colferai, Francesco Coradeschi +1
We derive the limiting form of graviton radiation in gravitational scattering at transplanckian energies () and small deflection angles. We show that --- owing to the gra…
Emerging Hawking-like Radiation from Gravitational Bremsstrahlung Beyond the Planck Scale
Marcello Ciafaloni, Dimitri Colferai, Gabriele Veneziano
We argue that, as a consequence of the graviton's spin-2, its bremsstrahlung in trans-planckian-energy () gravitational scattering at small deflection angle can be nicely…
