Asymptotic symmetries and subleading soft graviton theorem in higher dimensions
Dimitri Colferai, Stefano Lionetti
We investigate the relation between the subleading soft graviton theorem and asymptotic symmetries in gravity in even dimensions higher than four. After rewriting the subl…
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…

We generalize the semiclassical treatment of graviton radiation to gravitational scattering at very large energies and finite scattering angles , so as to ap…
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…
Rescattering corrections and self-consistent metric in Planckian scattering
Marcello Ciafaloni, Dimitri Colferai
Starting from the ACV approach to transplanckian scattering, we present a development of the reduced-action model in which the (improved) eikonal representation is able to describe…
Quantum Tunneling and Unitarity Features of an S-matrix for Gravitational Collapse
M. Ciafaloni, D. Colferai
Starting from the semiclassical reduced-action approach to transplanckian scattering by Amati, Veneziano and one of us and from our previous quantum extension of that model, we inv…
S-matrix and Quantum Tunneling in Gravitational Collapse
M. Ciafaloni, D. Colferai
Using the recently introduced ACV reduced-action approach to transplanckian scattering of light particles, we show that the -matrix in the region of classical gravitational coll…
interaction in light-cone gauge formulations of Yang-Mills theory in 1+1 dimensions
A. Bassetto, D. Colferai, G. Nardelli
A rectangular Wilson loop with sides parallel to space and time directions is perturbatively evaluated in two light-cone gauge formulations of Yang-Mills theory in 1+1 dimensions,…
