Description
We study in detail the explicit correspondence between solutions of the scattering equations and scattering amplitudes in four dimensions. We have established an interesting pattern in the solutions of the scattering equations. In particular, the MHV Yang-Mills amplitude, calculated from the CHY formalism, has support on only one particular well-behaved solution. For NMHV amplitudes and beyond, each of them can be obtained from an exclusive set of solutions, which do not intersect with others. Thus each solution corresponds to a basis amplitude, from which all the amplitudes can be constructed. We also attempt to give a geometric characterization of the sectors of solutions of the scattering equations.
