Infrared features of gravitational scattering and radiation in the eikonal approach
/ Ciafaloni, Marcello ; Colferai, Dimitri ; Veneziano, Gabriele
Following a semiclassical eikonal approach—justified at transplanckian energies order by order in the deflection angle ${\Theta}_{s}\sim \frac{4G\sqrt{s}}{b}\equiv \frac{2R}{b}$—we investigate the infrared features of gravitational scattering and radiation in four spacetime dimensions, and we illustrate the factorization and cancellation of the infinite Coulomb phase for scattering and the eikonal resummation for radiation.
