Scaling laws for the elastic scattering amplitude

, 2012
The partial differential equation for the imaginary part of the elastic scattering amplitude is derived. It is solved in the black disk limit. The asymptotical scaling behavior of the amplitude coinciding with the geometrical scaling is proved.

Crossing beyond scattering amplitudes

Journal of High Energy Physics
Abstract We find that different asymptotic measurements in quantum field theory can be related to one another through new versions of crossing symmetry. Assuming analyticity, we conjecture generalized crossing relations for multi-particle processes and the corresponding paths of analytic continuation.

Spinning waveforms of scalar radiation in quadratic modified gravity

European Physical Journal C: Particles and Fields
We study scalar–tensor gravitational theories using on-shell amplitude methods. We focus on theories with gravity coupled to a massless scalar via the Gauss–Bonnet and Chern–Simons terms. In this framework, we calculate the waveforms for classical scalar

Splitting CEGM amplitudes

Journal of High Energy Physics
The CEGM formalism offers a general framework for scattering amplitudes, which rests on Grassmannians, moduli spaces and tropical geometry. The physical implications of this generalization are still to be understood.
