Scattering amplitude as a function of the obstacle
AbstractLet Dj, j = 1,2, be two bounded domains (obstacles) in Rn, n ≥ 2, with the boundaries Г. Let Aj be the scattering amplitude corresponding to Dj. The Dirichlet boundary condition is assumed on Гj. A formula is derived for A ≔ A1 − A2. This formula is used for a derivation of the derivative of the scattering amplitude with respect to Г, the ...

Learning the simplicity of scattering amplitudes
The simplification and reorganization of complex expressions lies at the core of scientific progress, particularly in theoretical high-energy physics. This work explores the application of machine learning to a particular facet of this challenge: the task of simplifying scattering amplitudes expressed in terms of spinor-helicity variables.

4D flat-space scattering amplitude/CFT3 correlator correspondence revisited
In this paper, we make connection between CFT3 three point correlation function of conserved currents and 4D three point amplitude of general spin massless gauge field explicit.

Crossing beyond scattering amplitudes
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.
