Computation of contour integrals on ℳ0,n
(Springer Verlag, 2016-04-01)
Contour integrals of rational functions over (Formula presented.) , the moduli space of n-punctured spheres, have recently appeared at the core of the tree-level S-matrix of massless particles in arbitrary dimensions. The ...
Λ scattering equations
(Springer Verlag, 2016-06-01)
Abstract: The CHY representation of scattering amplitudes is based on integrals over the moduli space of a punctured sphere. We replace the punctured sphere by a double-cover version. The resulting scattering equations ...
